How to Match Tires to the Rim Size

31

Custom rims are great, but matching a tire to the rim can sometimes seem difficult. If you are changing rim sizes or looking to change tire sizes, the numbers can get confusing. For example, a tire size of 225/60R16 means that the tire is 225 millimeters wide (at the widest point of the sidewall), the aspect ratio (sidewall height) is 60 and the center hole diameter is 16 inches. Only two of the three measurements are needed to fit a tire to a rim: the section width and center hole diameter.
