How much is the tire pressure in winter VAZ 2114. What pressure should be in the tires of a car in winter and summer. About pressure values ​​in winter and summer

Pneumatic tires modern car are an invention, the uniqueness of which has not yet been surpassed by anyone over the past 170 years. The design options are changing, but the principle of air injection under pressure into the elastic dense shell of the wheel rim remains unchanged.

The Importance of Correct Tire Pressure

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

The air inflated into the tires affects several factors in the movement of the vehicle:

These points ensure safety vehicle, driver and passengers. A lot of troubles on the roads are due to the negligent attitude of car owners to the technical condition of the tires of their car. Incorrect tire pressure, in addition to violations of these aspects, leads to premature wear of the working surfaces of the tires.

These changes have an impact on tire performance and overall road safety.

Pressure ratings

The specifications set by the tire manufacturers are calculated empirically for maximum efficiency. They show that at the specified pressure, the tires meet all the safety, comfort and integrity requirements of the vehicle.

The pressure criteria specified by the vehicle manufacturers are based on the use of the vehicle at minimum load in normal atmospheric conditions. These recommendations are indicated in the instruction manual and are specific to the model and brand.

Pressure ratings depend on the following reasons:

• wheel size - R13,…, R15;
• location of wheels - front or rear axles;
• type of car suspension - front or rear wheel drive;
• workload - standard or maximum.

Features of tire inflation in winter

Seasonal changes in vehicle operating conditions also affect vehicle tire regulations. Affected by the temperature effect, when the pressure is automatically reduced in cold weather. The condition of the road surface and driving style must also be taken into account.

Let's note the main features of how to regulate tire pressure in winter:

• when pumping up indoors, you need to add 0.1-0.2 atm, since the pressure on the street will drop;
• for short-term movement on an icy section of the road, the pressure is reduced by 0.3-0.5 atm to increase the contact area of ​​the tire with the road surface;
• when the car is heavily loaded, the tire pressure should not be reduced, because the contact patch increases under the influence of the weight of the load;
• riding on flat tires in other cases is dangerous by spontaneous displacement of the tire from the rim;
• in large settlements where roads are treated with special reagents, pressure indicators do not change depending on the season;
• it is necessary to check the tire pressure at least once a week, and in case of sudden temperature changes - more often.

Consequences of changing tire pressure in winter

There are a number of myths about improving the performance of a car if we move away from the factory tire pressure indicators.

Some motorists lower their tire pressure in winter, believing that flat tires will provide a more comfortable ride. Consider the consequences of such an underestimation:

• the tire dampens the unevenness of the road worse, as a result the discs may be damaged;
• rubber wear increases, uneven wear of the tread occurs;
• the length of the braking distance increases, the controllability of the car worsens;
• as a result of invisible damage to the discs, an uncontrolled decrease in pressure occurs, which leads to catastrophic consequences.

Supporters of increased parameters believe that such manipulations improve the vehicle's cross-country ability in winter and save fuel. But there is also negative sides such an experiment:

• unevenness of the road surface is felt much more strongly;
• reducing the contact patch does not allow the protector to work fully;
• the directional stability of the car is seriously deteriorating;
• uneven rubber wear leads to its premature failure.

Deviations from optimal performance give a misconception about the performance of the rubber. The manufacturer knowingly indicates how much pressure should be. It is at the nominal figures that the performance of the declared quality parameters and performance properties is guaranteed.

Pressure characteristics versus wheel size

Naturally, different tire sizes will have different pressures. Domestic classic cars with R13 size have the lowest rates. Modern Russian models and foreign cars move on R15 wheels, in which the nominal value exceeds 2 atm. These parameters do not change either in winter or in summer, except in extreme cases when the pumping level is changed to drive along a problematic section of the road. More accurate figures, what pressure should be, is shown in the summary table:

Wheel size	Car make and model	Front wheel pressure, atm	Rear wheel pressure, atm
155/80 / R13, 165/80 / R13, 175/70 / R13, 185/60 / R13	VAZ 2101-2107	1,6-1,7	1,9-2,1
155/80 / R13, 165/70 / R13, 175/70 / R13, 185/60 / R13	VAZ 2108-2115	1,9	1,9
175/65 / R14, 175/70 / R14, 185/60 / R14, 185/70 / R14	Kalina, Priora, Granta, Renault Logan	2,0-2,2	2,0-2,2
185/60 / R15, 185/65 / R15, 195/50 / R15 ... 195/70 / R15, 205/65 / R15, 225/79 / R15,	Vesta, Largus, Ford Focus, Nissan Almera, Toyota Avensis, Corolla, Mercedes S-class, BMW 1-3 series, Audi A4-A7	2,3-2,8	2,3-2,8

When the vehicle is fully loaded, the pressure should be increased to maximum values. More specific manufacturer recommendations are indicated on the plates on the B-pillar on the driver's side of the door. When installing wheels of non-standard sizes on a car, it is necessary to correct the pumping according to the indicators of the new rubber. The table below will help you determine how much pressure to set in your tires.

Tire pressure monitoring

Regular checks of actual pressure are essential to ensure proper handling, ride comfort and tire durability. Everyday visual inspection will prevent a run-flat ride, which will be the last for rubber.

Instrument control is carried out monthly and before long trips in order to protect yourself from troubles on the highway. Check the technical condition of your car not only in winter, but also in summer.

Modern foreign cars are equipped with automatic pressure control systems with displaying indicators on-board computer... Older foreign models signal a decrease in this parameter with a special lamp on the instrument panel. Domestic car manufacturers have entrusted the responsibility of checking tires in the hands of drivers.

Professionals must have a pressure gauge in the car - a special device for measuring pressure. The pump level control can be checked at tire shops and at many petrol stations. There are also air compressors to normalize the tire pressure.

Be sure to check all the wheels of the car, not just problematic ones. Special attention should be paid to checking the tire pressure in winter.

High speed and traffic congestion oblige a modern motorist to be a competent and conscientious driver. Especially when driving in winter time a year when confidence in the technical performance of expensive foreign cars gives an imaginary guarantee of safe travel. It is necessary to strictly adhere to the recommendations of the manufacturers in terms of the technical condition of your car.

Probably every motorist knows how important is the "correct" tire pressure in a car. However, not everyone knows about the factors that affect tire pressure, as well as the features that must be taken into account when operating a vehicle.

According to the popular opinion of motorists, only the presence or absence of external damage to the tire or rim affects the tire pressure. However, in practice, there is a whole host of factors that, in their totality, can lead to significant differences in indicators. In this article, we will try to tell you about all the nuances.

What is tire pressure

At first glance, this question is the simplest one. Typically, tire pressure refers to the density of the air that is inflated in them or pumped. It, of course, has a pressure higher than in the surrounding atmosphere, and it is this difference that is the key value that ensures the performance of the wheel.

The advent of pneumatic wheels was perhaps the main invention made in the early days of the automobile industry. The tire inflated with compressed air made it possible to effectively smooth out road irregularities, ensure a high smoothness of the vehicle and damp shock loads transmitted from the roadway to the structural elements of the car.

Video - about the importance of maintaining the correct tire pressure in a car:

Solid wheels could not provide this, and to this day there are no technologies capable of providing similar performance characteristics, which are given by pneumatic wheels, with the corresponding simplicity and low cost.

In fact, from the very beginning, when such wheels began to be used on vehicles, engineers had a reasonable question about what tire pressure should be considered optimal for a particular car. And as a result, it became clear that for each category of vehicles, such indicators will be very different.

So what influences the selection of the optimal tire pressure for a car?

Vehicle weight

Perhaps this criterion is the main one, because the tire is designed to provide, first of all, effective absorption of the loads itself different types- percussion, vibration, etc.

Operating temperature

Everyone knows from the school physics course that gases tend to expand when heated, and at low temperatures - to reduce their pressure. Accordingly, the tire pressure must compensate for temperature fluctuations that occur during vehicle operation.

However, this statement applies not only to the range of external operating temperatures, but also to the fact that the tire heats up during rolling. By the way, the difference in temperature between the wheel of a stationary and a moving vehicle is very significant, and it is very easy to check it - just touch the wheel of the car. It turns out to be quite hot. In fact, this means that if the wheel is "over-pumped", in motion due to heating it can simply explode, which is very dangerous.

The location of the wheel on the front or rear axle

As you know, the axle loads for any car are different, and very significantly. The parameter of load distribution is called weight distribution and, despite the fact that from the point of view of optimal parameters, the best result is a weight distribution of 50x50, engineers cannot achieve this parameter even on sports cars with a center engine position within the wheelbase.

In practice, however, weight distribution can be influenced by many factors, including the number of passengers, load, etc. Accordingly, the load on the tires also varies over a very wide range.

Video - why measure tire pressure:

Taking into account all the mentioned characteristics, the vehicle engineers calculate the average tire pressure value, which is designed to "balance" these criteria and ensure uniformity of performance over the entire range of operating loads.

How to measure it correctly

A special device called a pressure gauge is used to measure tire pressure. It can be either mechanical or electronic, represent a separate device or be included in the compressor package, but its function remains the same - accurate measurement of the pressure created in the car wheel.

It goes without saying that the pressure gauge, like any mechanism for accurate measurements, has its own error. Its value is indicated on the body of the device, and the smaller it is, the more accurate the measurement made by the driver will be. In this case, the car manufacturer also indicates the recommended tire pressure for a specific vehicle in the accompanying documentation. Many tire manufacturers also provide their own recommendations.

At first glance, everything is simple - the driver only needs to adjust the tire pressure in accordance with the factory recommendations and maintain it at a given level. However, here we return to the fact that a number of factors affect pressure, and the main one is temperature.

Video - what can lead to the wrong pressure in the tires of the car:

In practice, this means that, having pumped up the wheels in the warm season to the standard value (for passenger car it varies, depending on the mass, from 2 to 2.5 atmospheres), with a decrease in temperature, we get a pressure that is significantly lower. It is especially problematic to "catch" the correct pressure if the car is stored in a warm garage. As a result, the wheels initially inflated to the correct value will change their physical properties during the trip, and when entering the heated box, the pressure will return to normal.

The solution to this problem can be the option when the tires are inflated after a long time, or compensating tire pumping in the box. However, the question arises as to how much the tire should be pumped so that in winter the pressure in the wheels is within the recommended range. Let's try to analyze this situation using examples of VAZ cars, which, as you know, have a wheel diameter of R13 or R14.

Tire pressures in winter and summer (table)

Automobile	Dimension of wheels	Summer tire pressure		Tire pressure in winter
		Front axle	Rear axle	Front axle	Rear axle
VAZ 2104	165 / 80R13	1.6	2.1	1.7	2.3
	175 / 70R13	1.6	2.2	1.7	2.4
VAZ 2108/09/99	165 / 70R13	1.9	1.9	2.0	2.0
	175 / 70R13	1.9	1.9	2.0	2.0
	155 / 80R13	1.9	1.9	2.0	2.0
Family VAZ 2110 and Lada Priora	175 / 70R13	1.9	1.9	2.0	2.0
	175 / 65R14	2.0	2.0	2.1	2.1
	185 / 60R14	2.0	2.0	2.1	2.1

The data in the table are for vehicles stored in a warm box. As you can see, the difference between the "summer" and "winter" pressure is about 0.1-0.2 atmospheres and it is this difference that is designed to compensate for the difference in thermal expansion and contraction of the air in the tire.

Despite the fact that we gave this example for popular VAZ models, a similar approach can be easily used for cars from other manufacturers.

What threatens the wrong tire pressure when driving a car

Very often, motorists underestimate the decrease in tire pressure of the car or their deviation from the manufacturer's regulatory recommendations.

In practice, the difference in tire pressure can lead to a deterioration in vehicle handling, increased tire wear, as well as a change in the balance of the vehicle when driving in corners.

The fact is that the uniformity of the tire pressure is an important aspect of the correct weight distribution of the vehicle. The pressure change is especially acute when driving on slippery surfaces and in winter time it can even lead to an increased "tendency" of the car to skid when cornering.

As already mentioned, not only reduced pressure can be dangerous, but also its increase. An over-inflated tire is often even more dangerous than an under-inflated tire. This is due to the fact that the wheel loses its elasticity and ability to effectively deal with shock loads from the coating.

As a result, driving a large bump at high speed can lead to an abrupt increase in pressure, which the tire will not be able to withstand. Thus, a wheel can explode in a relatively harmless driving situation.

As you can see, it is imperative to monitor the tire pressure. I would like to believe that this material will help you and answer the questions that may arise during the operation of the vehicle.

Inflated tires are a bad joke. I remember that in the morning I was looking at it, the rear wheels were lowered, but I had to go to a long distance truck. Drove at a gas station pumped up. And the weather was so-so: in the morning it was freezing slightly, and then in the afternoon it was hot in the sun. Well, I blew too much into one wheel for a hike, because I drive up almost to where I needed to, and grab a hole in the road with just this wheel. It’s so hot! Sound like a burst packet, I guess. There was no good oncoming lane. In general, the tire and fender liner were blown to pieces in general. I put the spare wheel on and ran on.

Nikolay

"In the garage, the wheels are warm" - and on the way, what are they cold? The wheels heat up pretty well while driving. If in frost -10-15 you drive 100-150 km on dry asphalt, and then move to a snowy parking lot, the snow melts under them.

Evgeniy

Such a simple, one might even say elementary, procedure will save a lot of nerves, time, and sometimes even lives. It was not for nothing that they came up with the idea of ​​prohibiting the operation of the vehicle with faulty steering. Wheels are part of it - and you need to be careful about this. And it is not difficult to monitor the tire pressure.

Oleg

I made it a rule to check the tire pressure daily before leaving the garage. It is on cold ones, as the manufacturer recommends. The only time I deliberately release the pressure is when driving on a terrible off-road (I have an SUV), it helps to overcome it.

Artem Popov

In my humble opinion, tire pressure is often not given enough attention. By drivers, this parameter is often considered unimportant, insignificant. Moreover, sometimes it is even quite explicitly and deliberately ignored. Meanwhile, tire pressure can be very important, if not "vital", because a wheel can easily burst from excessive pressure, which can cause an accident. However, an under-inflated wheel is no less dangerous than an over-inflated one. And the consequences of this can be just as unpleasant and even dangerous for the driver, passengers and others.

Lyokha

I think every experienced driver has chilling stories related to the condition of the wheels. Indeed, in fact, this is the first, most important factor of many others, affecting the safety of driving. Well, except for the "driver factor", of course. Experts say that for the characteristics of each road surface, for each weather situation, there are recommendations for tire pressure. It turns out that the driver must stop several times during the trip by pumping up and then releasing the pressure. Inconvenient? Well, yes, not really. Only life is dearer than any inconvenience. It is necessary to monitor the optimal state of pressure, first of all, in extreme conditions: ice, loose snow, rain, etc.

novel

It is necessary to constantly monitor the tire pressure. I know that an over-pumped wheel can do more trouble than an under-pumped one. Elasticity is lost and at high speed you can easily skid the car when driving on bumps on the road. Several times I saw a situation when the wheels of would-be drivers exploded. I think you should not neglect the safety of your own and your passengers, and occasionally, at least when changing seasons, check the tire pressure. For this there is a pressure gauge, the procedure is quite quick. If the deviation from the norm and the vehicle's handling will be significantly reduced.

Nikolay

Hello everyone! What can I say about the pressure - you need to regularly check it, but not to the point of madness, as some authors write here - to check it before each exit from the garage, this is already excuse the insanity. Every experienced driver can determine by eye if the wheel is "lying", at worst you can kick it with your foot. I also think that a decrease in pressure of 0.1-0.2 bar will not lead to anything critical. For example: if the specified axle pressure is 2.2, then a decrease to 2.0 is normal! But then you can already determine by eye. And of course, buy a monometer (not on a compressor), and a manual one - a small one for a quick check. Well, representatives of more expensive and newer cars are already using automatic tire pressure sensors with might and main. The same solaris are new - everything is already equipped with sensors, so nothing is required from the driver at all.

Oleg

Recently I just bought a car and I have to study various articles, but I have already experienced some of the problems myself. I drove 140 km, everything was fine, then the car stood in the parking lot for 5 hours, after going back I checked all the wheels, everything was fine. I drove 10 kilometers and felt that it was leading to the right. It turned out to have flattened the right wheel. The whole difficulty was that I did not know to what level to pump. Now I know that there is a plate with the norms on the door. In general, of course, it is better to study everything thoroughly about wheel pumping so that there are no unpleasant situations, now it is clear that this can even lead to an accident.

Anna

I myself faced a situation when in winter the sensor in the car began to show “check the tire pressure”. Of course, I immediately drove to the nearest service. The check showed that the pressure was within the normal range. It was then that I was told about the change in pressure at different times of the year.

Sergey

The pressure, in my opinion, should be checked in relatively warm weather, or in the garage. And pump up 0.1 atm higher than in summer. For in frosty conditions, the tires are often simply deflated. There is no point in pumping either - it will be tough and round like a donut, but we need the tread to adhere to the road with a larger area.
By the way, if it stalled somewhere, the following method helps: we lower the pressure of the driving wheels to 1-1.2 atm and slowly leave. The contact patch with the road is increased and the grip is improved. This allows you to crawl out of the snow captivity. Then we pump up the wheels to the norm.

Paul

When inflating car tires, I always inflate the tire pressure a little. Only 0.1-0.2 units. I noticed that the wheels lose a little pressure during operation, especially in winter, and after some time the indicators will become ideal. And here's an interesting story! I started to lower the tire slightly, pump it up and continue driving quietly for a couple of weeks, but when the wheel lowered again, I turned to the tire service. And I was surprised when the craftsmen removed the screwdriver's removable nib from the wheel !!! And it flew in at such a tricky angle that I didn’t notice it, looking at the wheel several times. The master left this detail in his collection, a piece of iron taken out of the wheels.

Natalia

Previously, I usually went to the tire shop to check the pressure and, if necessary, inflate the wheel. I bought a compressor 3 years ago. Now I monitor the pressure myself, especially before the long journey.

Sergey

Adjusting tire pressure, in addition to the standard, always depends on experience and on the duration of operation of a particular brand of car (just a habit). Basically, the whole theory is based on the use of new rubber, so wear and tear should not be forgotten, especially when buying used rubber. As wear increases, the pressure must be reduced or increased according to the ambient temperature or axle load. It is also necessary to monitor the wheel alignment - for example, if you notice that the rubber is eating up, and there is no way to go to the service station in the near future, then the pressure must be reduced and the driving speed must be reduced. in winter it is especially dangerous.

Michael

Tire pressure is important. It also greatly affects the ease of steering. If the steering wheel starts spinning tighter, I immediately check the pressure in the front wheels. And in general, I try to pump up the wheels once a week. Some slow down, poor seal on the rim of the wheel rim. Recently I went to a tire service and "cured" 2 of these wheels. But after seasonal storage in a set of wheels, at least one of them necessarily "gets sick" - apparently, rust forms on the disc.

Igor

Now such things are being sold - a unit that is installed in the cabin on the panel and four transmitters that are screwed onto the wheel valves. And always in real time, you can observe the pressure in all wheels, and if it starts to deflate, then a signal will follow. The cost of such kits is really not at all Divine, in the region of 10-15 thousand. Therefore, it is enough to buy a pressure gauge for fifty dollars to control the pressure and spend 10-15 minutes of precious time. Well, it is imperative to visually inspect the wheels every morning, assessing the degree of inflation, and indeed the presence of wheels 🙂

Lida

I had such a situation: I got into the car - the wheels were normally inflated (no visible changes in shape). And while I was driving, apparently one lowered a little…. as I later discovered. And so an unusual and incomprehensible knock appeared. After swapping, the knock disappeared. What could it be? Or was it not connected with the bus, but just coincided?

Igor

I noticed such a feature - the temperature drops a little (especially in the morning it freezes), the pressure gauge starts to show less than the norm, about 1.8 in the wheels, I pump them up to the norm of 2.0. And by lunchtime the sun is already up to almost 20 degrees plus, and the tire pressure of the car has already grown to 2.3. And if you also ride, then up to 2.5 rises on warm rubber. In general, a great thing is temperature! And what I wanted to say - do not rush to conclusions, having measured the pressure in the wheels. It is necessary to interpolate all the results for the season, for the average daily temperature, otherwise it will be necessary to pump up and lower the wheels three times a day 🙂

Gregory

I live in Siberia, so I already got into the habit of pumping the wheels up to 2.2 atmospheres in the rear and up to 2.1 at the front in winter, because during extreme temperature conditions the air loses pressure significantly, so I'm thinking, maybe if it will be more practical to pump nitrogen with nitrogen, comrades, what would you advise?

Tatiana

If you strictly follow the technical data, then you need to ensure that the tire pressure corresponds to them. However, in life this does not always coincide. If I take a car from the garage (it is not heated), then in the morning I look and set the pressure required by the manual. If I arrived at the dacha and I see a flat tire, then I either wait until the cylinders cool down, or I pump 0.2 atm more, because when it cools down, it will be the norm. As for the pressure gauge, it is better mechanical than electronic. Already changed 3 electronic ones and everyone is lying.

Denis

And my rubber was eating for about six months, I thought it might be similar collapse, and then I found the reason - riding on a flat tire!

SuperMakarij

Tire pressure is a serious thing. Many drivers focus on this either from the point of view correct operation car, and they are worried about extending the life of the tires. In principle, you need to think about this, but with an over-pumped wheel, get a tire explosion at high speed, but God forbid the front one - bad jokes. I had a case once, the rubber was worn out, but still looked decent. I asked the young locksmith at the tire changer to pump up, he pumped it up and as a result, a hernia formed on the inside, which burst on the road. It’s good that I didn’t go fast, everything worked out, but now I regularly check the tires and inflate them at least once a month, adjust and equalize the pressure in the tires.

Oleg

Tire pressure must be taken very seriously. If the tires are under-inflated - increased rubber wear, instability on the road, which is fraught with an accident on the track. An over-inflated tire - danger of explosion and very serious accident. Therefore, leaving in the morning, the first thing I do is look at the tire pressure and pump up, if anything, in full accordance with the instruction manual. It's another matter if you have to overcome snow drifts or a difficult-to-pass section of the road. Then just the case when you have to lower the tire pressure and sometimes quite significantly. This is to increase the contact area between the tire and the road to reduce spin. But just got out on a normal road, immediately pump up the tires to normal.

Laura

I have little driving experience, but still ... I always maintain the pressure in accordance with the manufacturer's recommendations. In non-standard conditions, I never pump up / do not reduce pressure, but I try to correct my driving style depending on the situation on the road. That's all…

Nikolay

I watch the wheels regularly, I don't check the pressure every day, but if I don't like something while driving, I definitely measure it. In the summer I try not to pump, there was a case when the wheel exploded. Uneven pressure is the unpredictable behavior of the vehicle on the road. Although it is difficult to determine with power steering, it all comes with experience. Usually starts to drift towards the tire with reduced pressure. There are all sorts of recommendations when it is better to pump, when to lower it, but all this brings benefits only in one key from a bunch of factors. In some cases, fuel is saved, but the suspension or the tire itself is worn out. All these manipulations should be carried out only if absolutely necessary. I try to keep my blood pressure normal both in winter and summer.

Sergey

I always ride with slightly under-inflated tires. In the summer heat it warns possible problems associated with high blood pressure. In winter, the grip patch increases on a slippery frozen road. For myself, I still noted that unevenly inflated tires deliver more problems than pumped or under pumped

Artem

I always control the pressure in the wheels, and try to keep it in the range of 2, the weight of the car is 1300 kg. Only in winter do I release the pressure to 1 in order to drive on snow or ice!

Maria

Bought new car in the cabin. While we were driving home, we rode every bump. Pressure 4 atmospheres. They called the salon, they said such norms

Egor

It is hardly worth checking the tire pressure before every exit from the garage, this is already too much. Imagine: before you go to work. in a suit and white shirt, you climb to the dirty wheels to measure the pressure.
If you let it down a lot, then you can see it by eye, and so - once a week, maximum. Usually, the wheel or normally holds pressure for a long time. or drops to zero overnight if a puncture happened.

Anatoly

So many years behind the wheel, and never heard of weight distribution! But I feel in which tire the pressure has dropped, noticeably in the course of the car.

Alexey Zayats

I myself faced such a problem. If the pressure is 1.5-1.6 in the tires, then at a rate of 2-2.1 this is not very noticeable, but their wear increases significantly, and even with uneven pressure, one wears out faster than the other. Now I go to the tire fitting once a week, pump up).

Vladimir Petenenkov

Previously, I did not attach importance to this, but as at gas stations they began to use tire inflation services free of charge, I began to use it right away. To be honest, it saves a little money on gasoline, the second is nerves, since the car behaves more adequately on the road. Well, yes! Rubber wears out less!

Maxim Sergeevich

A certain pressure does not have an exact standard. For example, when skidding in difficult conditions such as mud, especially in ditches, it is better to lower the tire pressure. This increases the adhesion to the soil, due to softening and streamlining. This approach also works in winter with slush, when the car is not yet completely buried and there is access to the nipple.

Denis

Many parameters of the car depend on the pressure in the tires: this is tire wear, fuel consumption, and cross-country ability in some cases.
It is especially important to select the appropriate pressure when the temperature changes in winter and summer.
Everyone is free to control the pressure independently, some put sophisticated tire pressure monitoring systems, someone uses a pressure gauge, but the most reckless are checked by eye.
I belong to the latter, i.e. sometimes every day (depending on the proposed route), sometimes every other day, I measure the pressure with a pressure gauge.
If it is necessary to inflate the tires, I am guided by the rate set by the manufacturer in the documentation for the car.
In winter, I only inflate the tires in the garage to avoid pressure differences and bring the pressure closer to ideal. And you also need to take into account the loading of the car.
However, sometimes it is simply necessary to relieve the tire pressure. Whether in winter or summer, when driving off-road, as this will significantly increase the cross-country ability.

Michael

I swing the front wheels to 1.8, the rear to 2.0. Recently I pumped up a wheel and a friend asked how much I pumped, I told him that they say so and so. To which I received the answer, the front tires should also be a bad grade, since the front is the engine. Whom to believe? The operation book says 1.8.

Macarius

I had a case. For a long time, driving the car out of the garage, I did not pay attention to the condition of the tires, especially those located on the starboard side. I accelerated along the highway strongly, at the turn I felt that I was not naturally shaken, the car somehow sank to my right side. I was confused, I almost jumped off the track. The front wheel was half deflated. Now I watch the tires in both directions.

Nikolay Vetrov

I check it once a week. The weather became capricious, heat in the daytime - cold at night. I also have soft tires, on the "eye" the tires are half-deflated. The difference in pressure is immediately felt on the front end. The car takes down, so, watch, do not be lazy. Wear is nonsense compared to an accident.

Sergey

Nowadays, there are simply many varieties of rubber and the determination of pressure for many becomes difficult, even if there are recommendations for a specific classification. In such cases, it is advisable to do pumping on new tires with a slight undershoot with running-in without special weight loads in order to determine the constant seasonal rate. Experience is needed for independent action.

Here I completely agree with Sergey. I had Kama rubber on my Niva, I kept the pressure as in the manual, about 1.9 atm, now I switched to KUMHO, and noticed that the rubber seemed to be under-pumped. Raised the pressure to 2 atm, it's still not enough, went to the tire fitting, the specialists say 2.2 is needed. I've been driving with this pressure for six months now, everything is fine. And so, usually I look visually, for 30 years of working as a driver, I can tell by eye whether the pressure is normal or not. In the morning, if it gets colder, I definitely pump it up, if it's hot, on the contrary, I bleed it a little and, despite the experience, I check it with a pressure gauge. I have a mechanical one since 1988, the glass is already cracked, but I won't change it for electronic, it hurts too much they lie.

To be able to pump up the tires at any time, I bought myself an electric pump that works from a cigarette lighter. Beauty in the forest or on a country road is not scary. You can always inflate the tire.

Basil

on hot tires I set the pressure to 2.2, in winter in the morning the pressure drops to 1.9 when driving it returns to 2.2, if on cold tires I put 2.2, then on heated tires the pressure rises to 2.5

Vladimir

Well, in fact, if you drive in the city, then there is no point in pumping up in winter and summer in different ways, absolutely no. I rocked 2.3 on Civic both in summer and winter.
It is much more dangerous when the pressure drops and if not strongly, then at first it is imperceptible. And it so happens that on one 2.3, on the other 2.0, on the third 1.8, etc. And this is at least uneven rubber wear, and in general the car itself can behave incomprehensibly, so I recommend checking the tire pressure at least once a week.

There is no need to reinvent the wheel. The tire pressure must be kept according to the car's instructions. I (Korando C 200) in winter (on a winter tire) and in summer keep 2.1 (round). True, the second winter will have to go on an all-season, so the pressure drops to 2.0 - this was enough for driving in the Donetsk region ...

Not every driver pays attention to the tire pressure of their car. But the safety on the road, handling and maneuvering of the car sometimes depends on what pressure in the tires. In addition, the tire pressure level affects:

• for fuel consumption,
• uniform wear of the wheel itself,
• may cause hernias on the wheel court.

If the pressure in tires r13 and r14 is increased, then, for example, when hitting an obstacle, the tire may even explode. Incorrect tire pressure r15 will also affect maneuverability when entering a corner, turning, etc. Best of all, at different levels of inflation of car wheels, the following figure will show.

Tire pressure

As you can see, already by the wear of the tread, you can determine what the problem of pumping the rim is, but it is better not to bring this up to this, but to maintain a certain atmosphere at the required values.

The tire pressure must be checked at least once a month. Professional drivers check every 2 weeks and before every long journey. A visual inspection wheels should be done daily before starting the car engine. Although, if you are a happy owner of low-profile tires, then it is impossible to determine what pressure should be in the tires by eye.

In recent years, tire and car repair specialists have advised purchasing tubeless wheels. But a decade ago, it seemed fantastic. To date, the operation of tires with tubes is isolated cases, and after a couple of years, wheels with a tube inside can be found, probably, only on a bicycle.

The tubeless tire has the best wear resistance characteristics due to the increased vulcanization. Due to their lighter weight, their technical characteristics are better due to less inertia. In addition, the tubeless tire balances better. Their service life is also longer. In addition, in the event of a puncture, the "tubeless" will keep the air longer, which will allow you to safely reach the service department.

Also, we will not consider the question of the need to ride winter tires with studs and with a greater tread depth in winter, because this affects your safety and the safety of not only the car, but the life and health of those around you. Therefore, in the summer we use summer wheels and no "all-season" in other periods, if you do not live in snowless Europe. The choice of a tire manufacturer's brand is your choice, the only thing worth paying attention to is that the radius of the wheels must exactly match the one recommended in the vehicle's service book.

The tires of the VAZ 2107 car are an important element of traffic safety. Their condition is determined not only by the integrity of the surface, tread depth, balancing, but also by air pressure.

Keep your tires pumped up

The pressure inflated into tires depends on how big they are. In addition, the pressure is also different for the front and rear wheels of the car. So, in relation to the VAZ 2107, for the front wheels it is 1.6-1.7 atm., for the rear wheels - 1.9-2.0 atm... Tires are checked, as a rule, at least once every two weeks.

The verification should take into account what external factors can affect the reliability of the measurements. These factors include the temperature of the ambient air and tires. The higher the temperature, the higher the pressure, and vice versa. Therefore, it is recommended to check without fail in case of significant temperature changes, for example, before winter.

To check and regulate the pressure, you must have the following instruments / equipment:

• Automotive pressure gauge;
• Compressor or pump.

Despite the fact that most car compressors have a built-in pressure gauge, the most accurate measurement result is obtained with a separate pressure gauge, since there are no extraneous forces, such as compressor pressure, during the measurement. If, according to the measurement results, the pressure is below normal, it is pumped up using a compressor or pump, if higher, it is released by pressing the spool, or a special button on the pressure gauge (if available).

Incorrectly adjusted pressure in the tires of the VAZ 2107, in addition to a threat to traffic safety, can lead to premature wear of the chassis or damage to the tires. As a result, repairs will cost hundreds of times more than timely control. It is also important that the wheel size matches design features cars. Sometimes, in pursuit of beauty, some motorists put wheels that are larger than the size allowed for this model, as a result, the chassis elements fail.

Advice when choosing a compressor - don't look at the size, not always big is powerful. Choose a compressor of the appropriate capacity, taking into account the volume of the wheels of your car. Also pay attention to what kind of working elements it has - plastic ones are less durable than metal ones.

Don't skimp on security

The quality of the rubber plays a very important role in safety matters. That is why you should not save where your health, and, possibly, life depends on it. Buy high-quality tires for your VAZ 2107 that provide excellent grip on the road surface. If you nevertheless decide to save money, buy good used rubber from world manufacturers instead of low-quality consumer goods. As practice shows, such a solution is more beneficial in all respects.

Pay attention to the damage that the tires receive during operation. It is not always possible to repair them. In some cases, it is better to completely replace the tire than to have a patch that can go off at any time and cause serious problems.

Repairing a tire will lead to wheel imbalance. Therefore, after vulcanization, it is necessary to balance it, otherwise vibration may occur during movement, which negatively affects the elements of the chassis and leads to their premature failure. This operation is also necessary after the disks are repaired (welding, rolling).

Special attention should be paid to the seasonal change of tires on a VAZ 2107 car. In winter, special Winter tires which are softer, do not harden in the cold and provide a secure grip even on slippery surfaces. In addition, special floating studs can be hammered into winter tires, for driving in icy conditions.

However, you need to be careful when using studded tires in winter - excellent grip on ice is replaced by reduced stability on asphalt surfaces. And the wear of the studs on the asphalt is accelerating. Experts say that quality winter tires provide better vehicle stability than studded tires.

The pressure in the tires of the vehicle must be checked regularly and maintained at the values ​​recommended by the vehicle manufacturer. A deviation from the established norm can lead to a variety of consequences, and most importantly, traffic safety depends on it. What pressure should be in the tires and what it affects, we will consider in a little more detail in this article.

WHAT IS THE THREATENESS OF DEVIATION FROM THE SET PARAMETERS

On front-wheel drive cars of the Volga Automobile Plant, such as VAZ 2110, VAZ 2114 and VAZ 2115, you can install wheels with a radius of R13, R14, R15 and R16, but normally the cars are equipped with only wheel disks and tires of the 13th and 14th radius. The optimal tire pressure depends primarily on the load and weight of the car, much more depends on road conditions and ambient temperature.

If the wheels are poorly pumped, then:

• The tire protector will wear out faster;
• It will become more difficult to steer the car and the steering wheel will be harder to turn;
• Fuel consumption will increase, and the more the wheels are deflated, the more noticeable is the consumption of gasoline;
• There will be a tendency for the car to drift, especially on a wet and snowy road, and stability will be lost;
• The power of the car will decrease, as the resistance to movement will increase.

If the wheels are over inflated, then this is also not very good:

• When driving, all the irregularities of the road surface are felt, the ride becomes uncomfortable. Besides chassis at the same time wears out faster;
• Due to less adhesion to the road surface, the braking distance is lengthened, which has a detrimental effect on traffic safety;
• The tire tread wears out unevenly, and the service life of the tires is noticeably reduced;
• A hernia on the wheel may appear, besides, under high pressure when hitting an obstacle, rubber may rupture, which is completely unsafe at high speed.

Below are three pictures that show how the rubber tread adheres to the road at optimal, low and overpressure.

Many car owners are wondering what pressure in R14 tires on VAZ models should be. According to technical conditions, wheels on a VAZ 2114 (2115) car are pumped up to 1.9 kgf / cm² (R13), on VAZ 2110-2112 cars, 2.0 kgf / cm² (R14) is recommended. Moreover, there is no difference on which axle the wheels are located - on the front or rear.

IMPACT OF WEATHER CONDITIONS AND ROAD FACTORS

The pressure in the tires of the VAZ in summer, in principle, should be the same as in winter. But in practice, in winter it is done a little lower for a number of reasons:

• Slightly flat tires allow better control of the car on slippery roads, it becomes more stable;
• The suspension is softened, and bumps in the road are not felt so;
• The braking distance becomes shorter, the likelihood of an emergency is reduced.

It is necessary to take into account the factor that after a temperature drop (after leaving a warm garage on a frosty street), the pressure in the R14 tires will decrease due to physical factors. Therefore, it should be checked before setting off, and if necessary, pump up the wheels. Also, when warmth comes after winter, pressure measurements should be taken.

The pressure in R13 tires in summer is usually maintained at 1.9 atm., But this level is designed for an average vehicle load (two or three people in the cabin). If the machine is fully loaded, then the pressure should be increased on the front axle up to 2.0-2.1 atm., On the rear axle up to 2.3-2.4 atm. The spare wheel is pumped up to 2.3 atm.

Russian roads are not of good quality, and therefore many car owners deliberately reduce the pressure in the tires so that all the irregularities of the road surface are not so noticeably felt when driving. Usually in the summer the wheels are "lowered" by 5-10%, and in the winter by 10-15% of the norm. On level tracks, you can adhere to the factory standard.

For example, a car tire pressure table

LARGE WHEELS

From the factory, the installation of wheels with a diameter of R15 and R16 is not provided, but some motorists are in pursuit of fashion and improved technical characteristics install them on their vases. And accordingly, you need to know what should be the pressure in the R15 tires, and what the pressure in the R16 tires. It all depends on the workload of the VAZ model. With an average load of the car, the wheels are pumped up to 2 kgf / cm², on a loaded car it is better to pump them up to 2.2 kgf / cm². And if a lot of heavy luggage is placed in the trunk, then the rear rubber is pumped up by another 0.2 kgf / cm². It turns out that the pressure in the R14 tires is approximately the same as the pressure in the R15 and R16 tires (for the VAZ 2110-2115 models).

MEASUREMENT METHODS

How to measure the pressure in the tires of VAZ cars? Measurement can be made using a special dial gauge, but it should be noted that they may have an error of 0.2 atm. The pressure gauge can be either a separate device or as part of a wheel pump.

Measuring pressure is very simple:

1. We reset the pressure gauge reading to zero;
2. We turn off the cap from the wheel spool (if any);
3. We put the pressure gauge union on the nipple and push;
4. We look at the indication of the arrow on the device.

The pressure may rise when the tire heats up. This often happens when the driver prefers a dynamic driving style with frequent and hard braking. Therefore, the measurement is made on the car before the trip, when the wheels are not yet warmed up.

INJECTING TIRES WITH NITROGEN

Recently, it has become fashionable to pump up wheels not just with air, but with nitrogen.

There is an opinion that:

• Nitrogen keeps the pressure more stable, and when the wheel heats up, it does not change in the tires;
• Rubber does not age longer, because the pumped air with nitrogen is cleaner;
• Steel wheel rims rust less;
• Reduces the likelihood of rubber bursting, since nitrogen does not support combustion and reduces the risk of explosion.

Therefore, it is hardly worth giving in to the persuasion of sellers of dubious services and throwing money down the drain. The only thing that you can be sure of is that the wheels will not be worse from pumping nitrogen. If you don’t mind the money, then you can try this innovation on your car.
