Tire Size Calculator
This tire size calculator will help you decide whether or not you might want to use a different sized tire on your car.
There are two modes: the normal mode will give you a range of different tire sizes which are within a certain percentage difference bigger or smaller than your current tire which you enter in to start. You may choose the same wheel diameter or a different one.
The second mode is to compare your original tire to a specific size
that you enter.
In both cases, the calculator will show you detailed calculations to
see the differences in the sizes.
