Tire Section Width: This number represents the section width of the tire across the widest point of the tire's outer sidewall to the widest point of its inner sidewall once mounted on the appropriate wheel. This number is in metric millimeters. To convert from millimeters to inches, divide the section width by 25.4. For example, a section width of 205mm is equal to 8.07inches (205mm/25.4 = 8.07inches).
Tire Size Sidewall: This number represents the tire size's sidewall height from the rim of the tire to the tread of the tire. A number of 40 indicates that the sidewall is 40% of the tire's section width. The higher the number is the taller the tire. This number can be referred to as the tires profile, series, or aspect ratio.
Tire Diameter: This number represents the tire's diameter. Tire and wheel diameters are designed to match. For example, a tire with a diameter of 17inches fits a wheel with a diameter of 17inches
