temperature resistance.
For more information, see
Uniform Tire Quality Grading on
page 10‑69.
(G) Maximum Cold Inflation
Load Limit
:
Maximum load
that can be carried and the
maximum pressure needed

Tire Designations
Tire Size
The following examples show
the different parts of a tire size.
Passenger (P‐Metric) Tire
(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 75, as shown
in item C of the light truck
(LT‐Metric) tire illustration,
it would mean that the tire's
sidewall is 75% 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.
