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.

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.
