Tire size calculator

You can compute tire size specifications through a handy form. It can tell you specific information about your current tires (if you know what the tire specification is) and tell you the difference between that and other tire specifications. This can help you determine approximately how incorrect your speedometer and odometer will be if you should change tires and rims.
