Tire size and rim tire size calculation

One of the numerical values that are standard for all manufacturers is tire sizes. We all know the values by heart like 225/40/17, but we cannot explain what they mean.
By giving an exemplary value, let's move on to our expression.

195-55-15:

Base Size:
It is the surface on which the tire comes into contact with the ground. It is indicated by numerical values between 55-365 (exceptions are of course). The unit of this measure is MM. That is, a 195mm surface of a 195-based tire is in constant contact with the ground.

Cheek:
In the example, it is the value that gives information about the profile of the tire, which is indicated with 55. This is a ratio, which is essentially a ratio of the base size over% 55. The sidewall means that there are 55% sidewall size of the tire.

Rim Size :
It is the size of the rim that can be used on the tire, it is stated that it is for the size of 15`` rim in the sample. It is not possible to use the rim other than given in the tire size, because in the automobile sector there are rim dimensions of 12``-22`` and in SUVs there are rim dimensions up to 30``.

When you want to change your tire and rim dimensions, you can find the least different sizes using the calculators below.
