Tire Size
The following examples show the different parts of
a 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.
(A) Light Truck (LT-Metric) Tire:
The United
States version of a metric tire sizing system. The
letters LT as the first two characters in the tire size
means a light truck 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 75, as
shown in item C of the light truck (LT-Metric) tire
illustration, it would mean that the tire’s sidewall is
75 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:
The service description
indicates the load range and speed rating of a
tire. The load index can range from 1 to 279.
Speed ratings range from A to Z.
