Example
TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental character-
istics of the tire and also provides the tire
identification number (TIN) for safety stan-
dard certification. The TIN can be used to
identify the tire in case of a recall.
Example
1. Tire size (example: P215/65R15 95H)
a. P: The “P” indicates the tire is
designed for passenger vehicles.
(Not all tires have this information.)
b. Three-digit number (215): This num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
c. Two-digit number (65): This number,
known as the aspect ratio, gives the
tire’s ratio of height to width.
d. R: The “R” stands for radial.
e. Two-digit number (15): This number
