Tire Designations
Tire Size
The following is an example of a typical passenger vehicle tire size.
(A) Passenger (P–Metric) Tire:
The United States version of a metric tire sizing system.
The letter P as the first character in the tire size means a passenger vehicle tire engineered to standards set by the U.S. Tire and Rim Association.
(B) Tire Width: The three–digit number indicates the tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio: A two–digit number that indicates the tire height–to–width measurements.
For example, if the tire size aspect ratio is 60, as shown in item C of the illustration, it would mean that the tire's sidewall is 60 percent as high as it is wide.
(D) Construction Code:
A letter code is used to indicate the type of ply construction in the tire. The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted–bias ply construction.
(E) Rim Diameter: Diameter of the wheel in inches.
(F) Service Description: These characters represent the load index and speed rating of the tire. The load index represents the load carrying capacity a tire is certified to carry. The speed rating is the maximum speed a tire is certified to carry a load.
