Optimal Tire Size Calculator

This part of the calculator automatically figures out the best three alternatives for your tires, based exclusively on the circumference of the tire. The minimum values are set and displayed for your information only, but you can adjust the maximum values so any tires found will be within the maximum width and profile that you specify. There is no guarantee that the selections found in your rim size will fit your vehicle. This calculator relies on having values filled in for "Current or original tire size" above.
