TIRE LABELING
Federal law requires tire manufacturers
to place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify the tire in case of
a recall.

1. P: The “P” indicates the tire is de-
signed for passenger vehicles. (Not all
tires have this information.)
2. Three-digit number (215): This num-
ber gives the width in millimeters of the
tire from sidewall edge to sidewall
edge.
3. Two-digit number (65): This number,
known as the aspect ratio, gives the
tire’s ratio of height to width.
4. R: The “R” stands for radial.
5. Two-digit number (15): This number is
the wheel or rim diameter in inches.
6. Two- or three-digit number (95): This
number is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires be-
cause it is not required by law.
7. Tire Speed Rating. You should not
drive the vehicle faster than the tire
speed rating.
