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.Tire size (example: P215/65R15 95H)

signed for passenger vehicles.
2. Three-digit number: This number
gives the width in millimeters of the
tire from sidewall edge to sidewall
edge.
3. Two-digit number: This number,
known as the aspect ratio, gives the
tire’s ratio of height to width.
4. R: The9R9stands for radial.5. Two-digit number: This number is the
wheel or rim diameter in inches.
6. Two- or three-digit number: 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.
