If you want to do a side-by-side comparison of two different tire sizes, simply enter your current tire size, followed by the new tire size. The calculator will provide the Sidewall Height, Section Width, Overall Diameter, Circumference, and Revolutions Per Mile, as well as an approximation of the difference in speedometer reading.
