Information Contained on the Tire
Sidewall
Both U.S. and Canada Federal
regulations require tire manufacturers
to place standardized information on
the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of the
tire and also provides a U.S. DOT Tire
Identification Number for safety
standard certification and in case of a
recall.

P215/65R15 95H is an example of a
tire size, load index and speed rating.
The definitions of these items are
listed below. (Note that the tire size,
load index and speed rating for your
vehicle may be different from this
example.)
A. P: Indicates a tire, designated by
the Tire and Rim Association, that may
be used for service on cars, sport
utility vehicles, minivans and light
trucks. Note: If your tire size does not
begin with a letter this may mean it is
designated by either the European
Tire and Rim Technical Organization
or the Japan Tire Manufacturing
Association.
B. 215: Indicates the nominal width of
the tire in millimeters from sidewall
edge to sidewall edge. In general, the
larger the number, the wider the tire.
C. 65: Indicates the aspect ratio which
gives the tire's ratio of height to width.
D. R: Indicates a radial type tire.
E. 15: Indicates the wheel or rim
diameter in inches. If you change your
wheel size, you will have to purchase
new tires to match the new wheel
diameter.
F. 95: Indicates the tire's load index.
It is an index that relates to how much
weight a tire can carry. You may find
this information in your owner’s
manual. If not, contact a local tire
dealer.
Note: You may not find this
information on all tires because it is
not required by federal law.
G. H: Indicates the tire's speed rating.
The speed rating denotes the speed
at which a tire is designed to be driven
for extended periods of time under a
standard condition of load and
inflation pressure. The tires on your
vehicle may operate at different
