Measure it. Put a piece of tape on the tire where it touches the ground, another one on the ground where the first is, then drive one (or several) tire rotations until the tape on the tire is on the ground again, and measure the distance. Divide by number of tire rotations you did.Trying Program Tire Size but just not getting it right what is the size in MM anyone is running that get's you close to spot on?
