Finally. A massive tire size chart with both metric and inch tire sizes listed to easily compare every tire size in one spot.

The following is an example to help to decode a tire size like 255/60R17. The 255 is the tire width in millimeters, measured from the bottom of the bead to the bottom of the bead, the 60 is the sidewall aspect ratio (the tire width factor), the ratio of sidewall height to tire width at the tread (indicating that the sidewall height is 70% of the tread width), and the 17 is the wheel rim diameter in inches.
For the measurements of your Original Equipment (OE) tire, or the current tire on your vehicle, simply enter the size. Our calculator will provide you with the Sidewall Height, Section Width, Overall Diameter, Circumference, and Estimated Revolutions Per Mile.
