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 very useful tire calculator when searching for tires that are a different size than stock.Īnother tire size calculator we have is our speedometer correction calculator.

The sidewall or aspect ratio are used in metric tire sizes to determine the overall height of a tire. The third number generally preceded by an 'R' is the wheel diameter. Divide this number by 25.4 to get the inch equivalent as there is 25.4 mm in 1 inch. The first number on a metric tire is the width in millimeters.
