Tire Labeling
The tires that came on your vehicle have a number of markings. Those you\

should be aware of are described below.
Here is an example of what each marking means:
P235/60R18 102V
•
P: vehicle type (P indicates passenger vehicle)
•
235: tire width in millimeters
•
60: aspect ratio (tire section height as a
percentage of its width)
•
R: tire construction code (radial)
•
18: rim diameter in inches
•
102: load index (code indicating maximum load
tire can carry)
•
V: speed symbol (code indicating maximum
speed rating)

n Tire Identification Number (TIN)
The tire identification number
(TIN) is a group of numbers and
letters that look like the example
below. TIN is located on the
sidewall of the tire.DOT B97R FW6X 2209
DOT: This indicates that the tire meets all
requirements of the U.S. Department of
Transportation.
B97R: Manufacturer’s identication mark
FW6X: Tire type code
22 09: Date of Transportation

n Glossary of Tire Terminology
Cold Tire Pressure – The tire air pressure when the vehicle has been parked
for at least three hours or driven less than 1 mile (1.6 km).
Load Rating –
The maximum load that a tire is rated to carry for a given
inflation pressure.
Maximum Inflation Pressure – The maximum tire air pressure that the tire
can hold.
Maximum Load Rating – The load rating for a tire at the maximum
permissible inflation pressure for that tire.
Recommended Inflation Pressure – The cold tire inflation pressure
recommended by the manufacturer.
Treadwear Indicators (TWI) – The projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread\
.
DOT Tire Quality Grading
The tires on your vehicle meet all U.S. Federal Safety Requirements. All\
tires are also
graded for treadwear, traction, and temperature performance according to Department
of Transportation (DOT) standards. The following explains these gradings.
n
Uniform Tire Quality Grading
Quality grades can be found where applicable on the tire sidewall betwee\
n tread
shoulder and maximum section width.
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform to Federal Safety Requirements in a\
ddit

ion to
these grades.
n
Treadwear
The treadwear grade is a comparative rating based on the wear rate of th\
e tire
when tested under controlled conditions on a specified government test\
course. For
example, a tire graded 150 would wear one and one-half (1 1/2) times a\
s well on the
government course as a tire graded 100. The relative performance of tire\
s depends
upon the actual conditions of their use, however, and may depart significantly from
the norm due to variations in driving habits, service practices, and dif\
ferences

in
road characteristics and climate.
n
Traction
The traction grades, from highest to lowest, are AA, A, B, and C. Those \
grades represent the tire’s ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concre\
te. A tire
marked C may have poor traction performance.
W

ARNING: The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration, cornering, hy\
droplaning,
or peak traction characteristics.
