Tire and wheel sizing tool

The tire size comparison calculator takes the measurements of two tires and compares the diameter, width, sidewall, circumference, and revolutions per mile.

Then as a bonus it shows examples of your speedometer reading with the first tire, and the actual speed you're traveling if you were to install the second tire. A very useful tire calculator when searching for tires that are a different size than stock.

Another tire size calculator we have is our speedometer correction calculator. This is valuable if you plan to or are already running bigger tires than stock, and want to know the speed you are actually traveling compared to you're speedometer reading. A bigger tire has a larger circumference, thus traveling a further distance for each revolution.

A speedometer reads the amount of revolutions your tires are making, not how far you are traveling. Therefore you are actually traveling faster than your speedometer says when you have larger tires than stock, and slower than you're speedometer says if you have smaller tires.
