Tire Designations
Tire Size
The example shows a typical
passenger vehicle 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 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
:
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.
Tire Terminology and
Definitions
Air Pressure
:
The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
