Tire calculator. How to calculate tires How to calculate wheel height based on tire size

03.01.2022

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 recalculating tire sizes using a calculator, keep in mind that:

With an increase in the diameter of the wheel rim (and, as a consequence, a decrease in the height of the tire profile so that the outer diameter of the wheel remains unchanged), the load on the car’s suspension increases, 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.

Car tires are an essential component of any car. They are able to ensure safety on the road, as well as the implementation technical characteristics, which were originally declared by the manufacturer. Every year drivers need to change summer tires for winter and vice versa. It is recommended to select tires with the sizes that were provided by the automobile company for a particular car model.
Today on automotive market We offer a wide range of tires that are produced by different manufacturers. They differ from each other not only in materials of manufacture and design, but also in size. Each car model has its own type of tires that are optimally combined with each other.
Tire dimensions usually mean three parameters - height (distance between the inner rim and ground), tread width and diameter of the inner hole (into which the disc fits). It is worth noting that the manufacturer, when determining sizes car tires takes into account their mass, thrust, power, width and purpose of use. If you allow even a slight deviation in tire sizes from the standard, this can lead to a number of changes, both positive and negative. For example, such as comfort while driving on a highway or dirt road, readings on the speedometer, fuel consumption and much more. It is for these reasons that changing factory tire sizes must be approached with special attention, because the consequences can be unpredictable.

Determining tire sizes using a tire calculator

  1. Select the wheel or tire sizes that appear from the drop-down list.
  2. Take a look at the sign below, which shows possible options replacements.
  3. From the drop-down list you need to specify the size of the disk or tire for the replacement option.

When choosing new tires for your car, first of all you need to find out whether the copies offered by the seller are suitable for the parameters of a particular car. It is easy to make such calculations if you use the free online visual 3D tire calculator in the KAMTECH online store.

We offer you a wide selection of tires and wheels for cars various brands and models, and with the help of our best tire calculator you will quickly find your bearings and be able to make the right choice.

How to use the tire and disk calculator in the KAMTECH online store?

Take a few simple steps: select the standard size of your car, as well as the sizes of the new tires (rims) that you want to purchase. Then click the "calculate" button. You will see the difference between tires (rims) and deviations in various indicators: diameter, width, circumference, profile height, and so on.

If the visual bus online calculator 3D showed a discrepancy between the parameters of tires and wheels according to the car make; you should select another model. Installation of tires not recommended manufacturer, may lead to incorrect operation of the speedometer, odometer or other electronic systems machines (for example, ABS, EBD and others). The car's handling characteristics may also deteriorate, which is quite dangerous, especially in winter.

If you install tires with a profile smaller than the standard one, the ride stiffness will increase, driving comfort will decrease, and the load on the suspension will increase.

In other words, the benefits of a tire calculator based on car brand can hardly be overestimated. It will save your time on selecting tires and wheels, will not allow you to make a mistake in your choice and waste money. Go to KAMTECH.RU - choose correct tires and buy them at a low price.

The first and second columns specify standard tire and wheel sizes. The remaining columns have the dimensions desired for installation. The calculator will help determine tolerances and alternative options selection

Tire calculator allows you to compare the dimensions of tires of different sizes. For example, choose wider tires, but keep the outer diameter of the wheel the same, or find out how much the vehicle's ground clearance will change if you install tires of a different profile.

To select an alternative size, you need to indicate the standard or existing tire size in one half of the calculator, and the desired or alternative size in the adjacent half.

The calculator displays the recommended rim width for a particular tire size, as well as the outer diameter and width of the wheel. Most important parameter- exactly the outer diameter of the wheel. You should pay the most attention to its changes.

The second important parameter is the actual height of the tire profile. It is usually expressed as a percentage of the width: for example, 205/55 R16, where 55 is 55% of the tire width. That is, 205*55/100=112.75 mm is the actual profile height of this tire.

Tires of different widths, standardly installed on a car, have different profile heights in percentages, but the same in millimeters. For example, tires with dimensions 275/40 R20 and 315/35 R20 have a profile height of 110 and 110.25 mm, respectively.

Some features of tire selection:

  • The wider the tires, the better the handling, but the resistance to aquaplaning is worse and the rutting is felt more strongly, and the comfort decreases - low-profile tires are stiffer.
  • Lower profile - heavier wheel. This is due to the fact that the disc is heavier than the rubber, the weight of the wheel increases and this worsens the performance of the suspension. In addition, the mass of the metal is distributed closer to the outer edge of the wheel and increases the moment of inertia (for cars with a powerful engine this is not significant).
  • As the profile increases, the car becomes more rolly, reacts worse to steering, but goes over bumps more easily, the tires are less sensitive to the sharp edges of holes, and comfort becomes better.
  • A significant change in the outer diameter of the wheel leads to distortion of vehicle instrument readings, in particular, mileage and speed.
