Tire Size

The following is an example of a typical passenger vehicle tire size.

(1) Passenger (P-Metric) Tire: The United States version of a metric tire

(1) 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.

(2) Tire Width:

The three-digit number indicates the tire section width in millimeters from sidewall to sidewall.

(3) 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 3 of the illustration, it would mean that the tire's sidewall is 60 percent as high as it is wide.

(4) 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.

(5) Rim Diameter:

Diameter of the wheel in inches.

(6) 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.
