Tire width is represented by a three-digit number on the wheels themselves. It is important to note that width is measured in millimeters. This three-digit number is followed by a two-digit number which is the aspect ratio. The wheel is measured from bead to bead. Finally, another two-digit number represents the diameter the tire was designed for. Interestingly enough, each wheel actually has 1/2 inch on each side more than specified. Therefore, a nine inch wheel is actually 10 inches in diameter. You can use this knowledge to determine which size wheel is right for you. For example, you can convert the real diameter of 10 inches to millimeters. In general, you want a nearly vertical sidewall when the tire is on the wheel.
