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 tire calculator 3D in the KAMTECH online store.
We offer you a wide selection of tires and rims for cars of various brands and models, and with the help of our best tire calculator you will quickly find your way and be able to make the right choice.
How to use a tire-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 wish to purchase. Then click the "calculate" button. You will see the difference between tires (disks) and deviations according to various indicators: diameter, width, circumference, profile height, and so on.
If the visual online tire calculator 3D showed a discrepancy between the parameters of tires and wheels for the car brand, you should choose another model. Installing tires that are not recommended by the manufacturer can lead to improper operation of the speedometer, odometer or other electronic systems of the car (for example, ABS, EBD and others). Also, the handling characteristics of a car may deteriorate, which is quite dangerous, especially in winter.
If you install tires with a profile less than the standard one, the ride stiffness will increase, the driving comfort will decrease, and the load on the suspension will increase.
In other words, the usefulness of a tire calculator by car brand cannot be overestimated. It will save you time on the selection of tires and wheels, will not allow you to make the wrong choice and waste your money. Come to KAMTECH.RU - choose the right tires and buy them at a low price.
With the help of a tire calculator, you can easily calculate how the outer dimensions of the wheel, the height of the ground clearance (clearance), the speedometer readings and other characteristics will change when tires with a different standard size are installed on your car. The calculator calculates all tire sizes in millimeters, and the vehicle speed in km / h.
And also the calculator will help to calculate the required rim width for a specific tire size.
How to use the tire calculator:
First enter the standard size installed on your car, and then the one that you want to install and click "calculate". The table on the right shows the results of the calculator's calculations.
Detailed information on tire marking in the section: tire marking.
We recommend that you only install the factory tire sizes that are specified in the operating instructions for your machine. Installation of non-standard sizes may void the dealer's warranty, as well as impair the performance and handling of the vehicle.

When converting tire sizes on a calculator, keep in mind that:
With an increase in the diameter of the 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 deteriorates (the car will become noticeably stiffer).
With an excessive increase in the profile of the tire, the car becomes a "roll", it is less controlled and at critical values of the height of the profile, the tire can begin to cling to the parts of the body and suspension of the car, which will subsequently lead to its destruction.
Some car owners eventually decide to supply discs with a larger diameter than originally envisaged at the factory. On the one hand, the car is being transformed, but behind the aesthetic beauty there is a technical error in the speedometer readings, which many either do not know about, or simply do not take it into account. This is of course everyone's choice, but you must admit that an unpleasant situation may arise when you drive your car, adhere to the speed limit, and the traffic police inspector who stopped you claims that you were driving with excess. Whom to believe, inspector or speedometer? Let's figure it out ...
The situation here can be twofold. If the installed standard size of tires and rims corresponds to the factory standards (approved by the manufacturer), then there should be no problems with the speedometer readings (if, of course, it is serviceable). But if the dimensions differ from those recommended by the manufacturer, then the inspector may be right.
Ideally, after installing non-standard tires or wheels, or both, on the car at the same time, you need to calibrate the speedometer. By default, manufacturers calibrate speedometers for those standard sizes that are indicated on the car body in the doorway from the driver's side, but if the sizes differ, then the speedometer begins to show not entirely reliable data.
The other day I came across a very interesting little program. The calculator of the error of the speedometer when changing tires and disks is an auxiliary tool for making the correct replacement of the disks and tires installed on the car. If you want to change the tire sizes or put wheels of a different radius, this program will help you find out how the external indicators will change, calculate the speedometer error, and show the changes in the vehicle's ground clearance (clearance).

Attention! Manufacturers and many car services do not recommend installing wide tires on the car during the winter season - this is due to the deterioration of the car's braking qualities.
Another useful tool is a rim width calculator. when changing the tire parameters, it is very important to check the compatibility of the wheel width of the vehicle mounted on the vehicle. In the worst case, you simply will not be able to pull the rubber onto the rim. This small calculator will help you calculate the minimum and maximum wheel widths suitable for the selected tire size.

Operating with these two calculators, you can easily determine the standard size of car tires or choose new rims for the required tire size.
Perhaps, for today this is all that I wanted to show and tell you.
Attention # 2! The calculator for calculating the error of the speedometer and comparing tire sizes is provided for informational purposes only and does not guarantee 100% correct data. Contact a tire specialist for advice !!!
Thank you for your attention and interest in the project.

P.S. According to the good old tradition, do not forget to subscribe to updates on my blog and, tell friends about the project, share links to interesting posts on the network, leave detailed comments on the topic, do retweets, put likes, click on "I like", add posts to Google plus and ... And of course, the MOST IMPORTANT - visit !!! There is already a lot of interesting things, but there is a lack of active live communication and interesting topics of discussion. I will be glad to any help in its development and filling.
