Car tire pressure table VAZ 2115. Tire pressure in winter and summer. Dependence of tire pressure on climatic and road conditions

The domestic auto industry rarely pampers us with novelties of vehicles, so there is no particular variety of Russian cars on the roads. However, many motorists who own cars such as VAZ 2107 or 2114, or 2115 do not seek to part with them and for many years roam them across the vastness of Russia. What is the reason for such popularity of Lada in our time - this is the second name of these machines, no one can explain. Everyone has their own reasons not to part with an "old friend".

Since many VAZ car models have not rolled off the assembly line for a long time, it is not necessary to expect that they will be equipped with the latest functions. Naturally, the safety in them is a complete misfortune, except for the seat belt, there is no protection. Experienced drivers increase the percentage of their life safety by always monitoring the tire pressure of a VAZ car. In addition, this allows you to reduce the wear and tear of the transport, which is important.

Influence of tire pressure on safety

It is impossible not to assess the correctness of the pumping of the wheels, because this has a significant effect on the condition of the components of the car, as well as on the safety of the driver, his passengers and other road users.

• If the tires are inflated differently, not corresponding to the values ​​indicated in the passport for the vehicle, then the car may behave unpredictably while driving.
• When a lot of air is pumped into the wheels and the pressure goes off scale, then there is a high probability of tire rupture. And when driving, the braking distance is greatly increased, the dynamic performance deteriorates.
• Lack of air is no less dangerous, especially in the cold season, as the stability of the car and cornering deteriorates, and there are also problems with extreme braking. The pressure in VAZ tires in winter should be slightly higher than in summer.

All this leads to serious consequences and terrible accidents.

• Improperly inflated tires wear out faster.
• Since the dynamics of the car deteriorates, as a result, more fuel is consumed.
• Driving becomes worse, especially in winter and on wet surfaces.
• The quality of braking suffers.
• Suspension damage is very likely if it falls into holes in the road.

Do not pump the wheels or not pump them. This could cause death or serious damage. Particular attention should be paid to lovers of Lada cars, which are not distinguished by their safety.

What about the WHA?

The optimal pressure in the tires of a VAZ 2107 will differ from the pressure in the tires of a VAZ 2114 or any other car. This is due to the fact that each car has its own weight, disk size. In addition, operating conditions and other factors must be taken into account. That is, everything matters: the season, the climatic zone, the load, etc.

In order to inflate the wheels as correctly as possible, this is especially important in winter, you need to look at the vehicle operating instructions. There is information about which wheels need to be installed on the car and what air pressure should be in them for normal driving.

It is worth paying attention to the tires, as a rule, on their lateral side there are extremely permissible pressure values.

In VAZ cars, the majority wheel rims have a radius of 13, which is designated R13, but at the same time they need to be inflated in different ways.

Automobile model	Tire size		Optimal tire pressure
	Front pair	Back pair	Front pair	Back pair
VAZ 2107	165/80 R13	165/80 R13	1.6	1.9
	175/70 R13	175/70 R13	1.7	2.0
VAZ 2114/2115	165/70 R13	165/70 R13	1.9	1.9
	175/70 R13	175/70 R13	1.9	1.9
Lada Kalina	175/70 R14	175/70 R14	1.9	1.9
	185/60 R14	185/60 R14	1.8	1.8

Tire pressure Lada in winter and summer

Car manufacturers do a great job of calculating the optimal tire pressure, so there is no reason not to trust the written information in the passport for the car. Especially carefully this issue was approached in Soviet times, when the production of Lada cars began.

Pressure gauge

Although many motorists have their own opinion on this matter and believe that it is necessary to adjust the inflation of tires depending on the season and the rubber used.

• Winter tires are a little softer than summer tires, so it is recommended to pump them harder.
• When driving on winter roads, the indicators should be slightly higher than normal.
• In the summer, it is advisable to lower the pressure a little, since when the air is heated it expands.

Listening to the opinion of experienced drivers or clearly following the recommendations in the car passport is a purely individual matter. One thing is for sure - one cannot deviate greatly from the optimal values, no more than 10-15% is permissible

How to measure pressure

In cars such as the VAZ 2107 or VAZ 2114, of course, there are no automatic monitoring systems already installed at the factory. Therefore, the driver must take care of himself.

for measuring tire pressure

There are several types of devices that can monitor tire pressure. They have different capabilities, which accordingly affects the cost and usability.

• For those who value their life infinitely and safety for them is not just a word, there are special tire pressure monitoring systems. Their installation is not easy and the cost is high, but positive qualities weight. They allow not only to inflate the tires perfectly, but also to monitor any changes in pressure, which makes it possible to timely eliminate all deficiencies and problems.
• Various types of pressure gauges: mechanical, electronic, should always be in the arsenal of any driver. Each type has its own pros and cons, as well as a significant difference in cost.
• The most primitive devices are cap devices. They do not show exact numbers, but their color scale will indicate whether the pressure in the tire is normal or not.

Every driver in his lifetime manages to try all types of devices and chooses the most convenient model. Do not forget about the accuracy of the device, not all of them differ in it, as well as the specifics of use.

For a long time, VAZs will drive along our roads, deftly maneuvering between proud foreign cars. Indeed, despite the lack of advanced options in most models, they have proven themselves well. And if their drivers still pay close attention to the tire pressure of VAZ cars, then driving safety will be higher.

The recommended tire pressure of the car can be found in a special table located in the instruction manual. vehicle... Depending on the car brand, manufacturers indicate the optimal pressure at which the load in the tires will be evenly distributed.

The concept of tire pressure should be understood as the density of the air pumped into the tire by the compressor. It is necessary to inflate tires taking into account the data of tables of pressure in tires of passenger cars and trucks... The correct pressure ensures an even distribution of the load, affects the following parameters:

• fuel consumption;
• uniformity of tire wear;
• safety of movement of the machine.

There are several options for which the specified parameter will not be optimal:

• tires are inflated - the density of the inflated air is too high;
• underdeveloped tires - this parameter is underestimated;
• all wheels of the car have different pressures.

Correct pressure ensures reliable adhesion of the tires to the road surface and affects the comfort and safety of movement. Find out how wrong pressure Tire effect on tire wear is possible by looking at Figure 1.

Figure 1. Influence of tire pressure on tread wear

In the first variant, the tire is under-inflated to the permissible rate, excessive wear of the tread along the edges of the rubber occurs. In the second version, the tire is inflated to the required rate - the tread wear is even. The third option shows an over-inflated tire - the middle part of the tread wears excessively.

In real operation, after twenty minutes of driving at high speed, the tire pressure increases by 0.5 atmospheres. Long journeys at high speeds can lead to an increase in the specified parameter up to 4-5 atmospheres. In such a situation, an over-inflated tire may burst while the machine is moving.

Lowered to half the atmosphere of the wheels can affect the "behavior" of the car, the risk of accidents increases. It is recommended to check the tire pressure once a week, as well as before long trips.

Influence of various factors

You can check the air density of the tires using a pressure gauge. It is recommended to carry out this procedure inside a garage or box with cold tires. The temperature difference between the moving and standing wheels is significant: while driving, the tire heats up. In this case, the air supplied inside it has the ability to expand when heated and reduce its volume during cooling.

Tire Air Density Measurement Procedure

From a theoretical point of view, pumping up the wheels to normal pressure values ​​is not difficult. From the practical point of view, everything is not so simple: having inflated tires on the street to an acceptable value in winter, you will notice that during the trip, the pressure inside the tires will change. It is possible to solve this problem by pumping up tires in winter inside a warm garage or box after two hours of inactivity of the car.

In summer, the cooling of tires is very slow, so the wheels are pumped up after the trip when the tires have completely cooled down. Many car enthusiasts argue that the permissible tire pressure is different in winter and summer, therefore, in the summer, you need to under-pump the tires to the permissible norm, and in the winter - to pump the tires. This is a misconception. The tire pressure recommended by the vehicle manufacturer is the same in winter and summer, motorists need to monitor this parameter and try to keep it within the normal range. Under-pumping or over-pumping of wheels leads to a deterioration in the adhesion of tires to the roadway, and reduces the tire life.

The tire pressure is influenced by the location of the tires on the front or rear axle. The axle load of the vehicle differs significantly. An even distribution of the load is called weight distribution, it is optimal if 50% of the loads are on the front axle and the same amount on the rear, but in real conditions it is impossible to achieve such a distribution of loads. Therefore, the load on the tires of the front and rear axles is different, for example, compare the data in the tables below.

Pay attention to the optimal parameter of the density of the injected air, influenced by the car brand, the location of the tires on the front or rear axle, the size of the tires (for radii R13, R14, R15, R16 .. the specified parameter is different) and the load of the car.

Conclusion

The fuel consumption of the car, the load on the chassis, the resource of tires, and controllability depend on the pressure in the tires. An increase in the ambient temperature leads to an increase in the density of the air injected into the tires; with a decrease in the air temperature, a decrease in the tire pressure is observed. Therefore, the density of the air with which the tires are inflated is checked after the rubber has completely cooled down: tires cannot be pumped immediately after a long trip. In winter, pump up tires in a warm garage or box, so you get as close as possible to the optimal density values.

In case of large differences in air temperature, measure the specified parameter more often. Consider: the load on the tires, regardless of the season, increases when the car is fully loaded, so adjust the density of the air pumped into the tires depending on the operating conditions of the vehicle.

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 only wheel rims and tires of the 13th and 14th radius. The optimal tire pressure depends primarily on the load and weight of the car, and much more depends on the 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 skid, especially on wet and snowy road, 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, the 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.

The manufacturer of both the car and the tires always recommends adhering to a certain pressure in the wheels, and the pressure in the tires both on the front and on the rear axle does not have to be the same. It all depends on the load on the car, weight distribution, weather conditions.

If the wheel has great pressure, then:

1. The coefficient of resistance decreases.
2. Less subject to deformation.
3. The point of contact with the road decreases.
4. Low shock absorption.
5. High controllability.

If the wheel is at low pressure:

1. The point of contact with the road increases.
2. The coefficient of resistance increases.
3. Consumption increases.
4. More comfort on uneven roads.
5. Low controllability.

The tire consists of 2 main parts: Tread and sidewall. The protector is a dense material that is not susceptible to deformation. The sidewall, on the other hand, suffers greatly from both low and high pressure.

At low pressure, the fact that on a bump or hole the rim of the disc will cut through the tire is not excluded, and you, at best, will not be able to continue driving on such a "wheel". And at high pressure, on impact, a hernia can jump out or just burst. But we are talking about a pressure 2 to 3 times higher than the norm, if you pumped the tire by 10-15%, then there is nothing catastrophic in this.

What should be the air pressure in the tires?

r13

r14

r15

The tire pressure setting does not depend on the radius and size of the tire, but depends on the load. Therefore, the values ​​for all radii are approximately the same. The manufacturer recommends setting the pressure at 2 (kgf / cm 2).

For a more accurate determination of pressure, see the formula in the table.

How and how to measure tire pressure?

There are two main ways to measure tire pressure:

• Using a pressure gauge.
• By means of a pump with a pressure gauge.

In both cases, you need to do the same operations:

1. Remove the cap (if present).
2. Remove the cap or spool on the nipple.
3. Depressurize the pressure gauge using the button.
4. Slide a pressure gauge or pump onto the nipple.
5. We look at the readings.

Each gauge has an error of 0.2 bar.
