Tire Labeling

Federal law requires 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 tire identification number for safety
standard certification and in case of a
recall.

P215/65R15 95H is an example of a tire
size and load index rating. Here is an
explanation of the various components of
that tire size and load index rating. Note
that the tire size and load index rating may
be different from the example.

P

Indicates a tire that may be installed on
cars, SUVs, minivans and light trucks as
designated by the Tire and Rim
Association (T&RA).

NOTE

If your tire size does not begin with a letter
this may mean it is designated by either
ETRTO (European Tire and Rim Technical
Organization) or JATMA (Japan Tire
Manufacturing Association).

215

“215” is the nominal width of the tire in
millimeters. This three-digit number gives
the width in millimeters of the tire from
sidewall edge to sidewall edge. In general,
the larger the number, the wider the tire.

65

“65” is the aspect ratio. This two-digit
number indicates the tire's ratio of height
to width.

R

“R” is the tire construction symbol. R
indicates “Radial ply construction”.
