This table shows tire width (mm) and wheel diameter (in) in the left 2 columns, and in the main cells are the overall tire diameter and the percentage difference from stock:
(Values 10 or more percent different than stock have been eliminated for clarity. Realistically no diameter more than 5% bigger or smaller should ever be used.)
