How to use a tire disc calculator

Visual tire calculator offers tire comparison different sizes. The calculator is very easy to use. As you can see, the tire disc calculator is divided into two parts. The top area of the calculator includes fields for selecting tire and wheel options, as well as a graphical representation of the wheel, where changes are displayed on the fly once all sizes are determined. And the lower area, which offers a complete table of wheel sizes of different diameters with tires of different widths and profiles that could fit your given size recommended by the manufacturer of your car. The presented size table of possible tires and wheels allows you to quickly obtain information about the dimensions suitable for the car.

The main problem that it solves tire and disk calculator, it allows you to select a “cheap” tire size. For those who don’t know, there are expensive tire sizes and cheap ones, but they are cheap not because the tires are bad or the production date is ten years old, but because the sizes are not popular with manufacturers, although the changes from the manufacturer’s recommended size will be very minor. Using the calculator's readings, you can quickly determine the cheapest tire size for your car, after which it will be easier to decide on the manufacturer.

If with summer tires inexpensive options can be found in any size, since no pattern has been identified, then in relation to winter tires everything is more or less obvious. If you add 5% of the profile height from the tire size recommended by your car manufacturer to search for original size. For the same manufacturer of car tires, the difference in sales price can be up to 30%. The calculation formula is simple: the higher the wheel profile (within reasonable limits), the cheaper it can cost.

A virtual tire calculator for wheels and tires will help you make the right choice!

Service users do not need to make complex independent calculations of the difference in permissible sizes tires and wheel offset, the disc tire calculator provides a detailed comparison table between the recommended size and the desired size, based on which you can easily make your choice.

In addition to the visual tire calculator, our website contains other online services useful for car owners.

When selecting new wheels for a car, the question often arises: should I get larger or smaller wheels, or for the purpose of improvement? appearance cars or cheaper purchases of tires and wheels. But the most important question arises: will the wheels be suitable for my car and how its characteristics will change. You can find out whether the wheels will fit on the gas tank cap or the side pillar of the car (photo 1). Or find your car in our directory of wheel applicability for cars and see the tires recommended by the factory. But it often happens that you can supply other tires that are not officially approved by the factory.

In this case, the main thing is to understand how the speedometer indicators will change, i.e. the speed of the car, since the outer radius of the wheel will change. The ground clearance (ground clearance) will also change. It is not recommended to go beyond the factory tire values by more than 2-3%. The vehicle's handling and behavior, gas mileage, and actual vehicle speed may change.

Tire calculator - size comparison

Our tire calculator will show you visual differences in tire diameter, profile, radius, ground clearance and tire width. The dotted lines indicate the difference in size. At the top you can see a visual representation old tire(original size), and the new tire is visualized at the bottom. Just as you noticed, the tire can be seen in the side and frontal projections. You can copy the page address and show it to other people and they will see the same comparison as you see.

But how to understand all these values and the difference in %? For this purpose, we created a tire calculator; it will help you understand the change in all the necessary characteristics and will show the difference in % between the old and new tire and even visually display what the old and new size wheel will look like. You just need to enter the tire width, profile and wheel radius. Usually they are displayed in this form - 195\65 R15 (photo 2).

How to use the online tire calculator?

Our online tire calculator is very easy to use. In the upper left corner of the site, there are fields for selecting the tire size. In the top row you need to indicate the size of your original factory tire (or the tires currently installed on your car). These values are written on the tire profile (sidewall). In the first list you need to select the tire width - it is indicated in millimeters. The second list is the percentage of the profile height to the tire width. The third list is the diameter of the disk in inches (commonly called radius).

In the bottom row you need to indicate the size of the new tires. Tires that you are going to install on your car or have already purchased. After that, click "Calculate". Our tire calculator will calculate the differences between the old and new tire and display them in a table and picture. Namely: diameter, width, circumference, tire profile height, number of revolutions per kilometer and change in vehicle clearance. The first columns of the table will show the parameters for old and new tires, the following columns will show the difference in mm and the percentage difference between them.

At the bottom of the tire calculator there is a speedometer to visually compare the speed of the old and new tire. Under the speedometer, you can increase and decrease the speed and see the changes in the speed difference between the old and new tire.

Be careful!

Be careful on the road and follow the manufacturer's recommendations. The reverse side of the installation is not standard sizes tires, there is a risk of losing insurance in case of an accident, failure to pass a state technical inspection of the car, since the installation of tires not approved by the factory is considered a change in the design of the vehicle.

Using a tire calculator you can easily calculate how the following will change: the external dimensions of the wheel, the height ground clearance(clearance), speedometer readings and other characteristics when installing tires of a different size on your car. The calculator calculates all tire sizes in millimeters, and vehicle speed in km/h.
The calculator will also help you calculate the required rim width for a certain tire size.

How to use the tire calculator:

First enter the standard size installed on your car, and then the one you want to install and click “calculate”. The table on the right will show the results of the calculator's calculations.
Detailed information about tire markings in the section: tire markings.

We recommend that you install only the factory tire sizes that are listed in the owner's manual for your vehicle. Installing non-standard sizes may void the dealer's warranty, as well as degrade vehicle performance and handling.

When converting tire sizes using a calculator, keep in mind that:

With increasing diameter wheel rim, (and, as a consequence, reducing the height of the tire profile so that the outer diameter of the wheel remains unchanged) increases the load on the car’s suspension, and comfort also worsens (the car will become noticeably stiffer).

If the tire profile increases excessively, the car becomes “rolly”, handles worse, and at critical values of the profile height, the tire may begin to cling to parts of the car body and suspension, which will subsequently lead to its destruction.

You may need such a calculator if you want to install instead standard tires or similar disks, but of a different size. With its help, you can visually represent dimensional changes and only then interpret them for a specific car. At the same time, the calculator is not a tool for selecting tires and wheels, since it does not contain a database of manufacturers.

When replacing wheels and tires, taking into account geometric data obtained from tire calculator, it wouldn’t hurt to take a few measurements yourself. Firstly, the distance from the suspension to the wheel surface is inside, as well as from the shock absorber cup to the tread surface. Secondly, from the wing, as well as steering rods to the tread surface. In this case, the geometric parameters of the new wheel assembly should not greatly exceed the size standard tires and disks. Otherwise, the vehicle may behave unstable.

A few basic rules to remember when replacing tires and wheels.

Tread summer tires standardly has a depth of 0.8-1 cm;
When installing disks with a larger diameter than standard ones, it is necessary to reduce the amount of offset - for every inch of height, 3 mm of offset;
Often the hub holes on discs that are not original have a larger diameter. Therefore, when installing them, you need to use special rings for fixation;
In the case where the hole on the disk is smaller than the hub mounts, it is strictly forbidden to drill them out, as well as grind the hub itself;
Correct selection of non-original wheels using a calculator will allow you to maintain the driving characteristics of the car;
If you are not sure about the compatibility of tires or wheels with your car, it is better not to install, or seek help from specialists.

Instructions

Look on the nameplate in the driver's side doorway for the recommended tire size. Write it down on paper or remember it. Find wheels of this size in a car dealership and use a tape measure to measure the outer diameter of the tire. Write this value down on paper. Drive the car into the pit and turn the front wheels completely: first in one direction and then in the other direction. Use a ruler or tape measure to measure the distance from the tire to the nearest structural element and write down these values on paper.

When choosing the tires you like, take into account the diameter of the future rims, and, depending on the size of the future tire, select the width of the rims. The required wheel width is equal to the tread width. It may be easier to find a disc with a slightly larger diameter and the width you need. For example, take 14-inch wheels instead of 13 and choose tires for them. This option will be even more advantageous in terms of durability, but it will be more expensive.

Try to buy tires overall dimensions which will be approximately the same as the recommended ones. For example, the manufacturer recommends tires with dimensions 175/70R13 86S. 175 is the overall width of the tire in millimeters, /70 is the height of the tire profile as a percentage of the width, R-13 is the mounting diameter corresponding to the diameter of the rims, 86 is the load factor, S is the speed index. It is worth noting that the overall width of the tire may differ from the tread width, so if you want a wider tread, then pay attention to this feature. Do not buy tires with low load and speed coefficients.

If you want to put R16 wheels on your car instead of R13, find tires of the appropriate width. Since there are no 175mm wide R16 tires, it is more realistic to find tires 215mm wide or wider. Look at your notes and calculate how many centimeters you have left. Increasing the tire width by 1 cm more than recommended reduces the measured distance between the wheel and the body by 5 mm. Please note that it is not advisable to increase the wheel diameter by more than 3 cm, as this will lead to increased consumption fuel and deterioration of the vehicle's traction characteristics. Select suitable tires and measure their diameter with a tape measure. Compare with recommended wheel diameter. If the recommended dimensions of the future wheel are exceeded within your calculated norm, you can safely buy the selected tires. The speed and load coefficient in this case will significantly exceed the recommended one, which will have a beneficial effect on the durability of the rubber.
