DOT Tire Quality Grading (U.S. Cars)

The tires on your car meet all U.S.

Federal Safety Requirements. All
tires are also graded for treadwear,
traction, and temperature perform-
ance according to Department of

Transportation (DOT) standards.
The following explains these

gradings.

Uniform Tire Quality Grading

Quality grades can be found where
applicable on the tire sidewall

between the tread shoulder and the
maximum section width. For

example:

Treadwear 200

Traction AA

Temperature A

DOT Quality Grades

All passenger car tires must conform

to Federal Safety Requirements in
addition to these grades.

Treadwear

The treadwear grade is a compara-

tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified government
test course. For example, a tire
graded 150 would wear one and one-
half (11/2) times as well on the
government course as a tire graded

100. The relative performance of

tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm
due to variations in driving habits,

service practices and differences in
road characteristics and climate.

Traction AA, A, B, C

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 concrete. A tire
marked C may have poor traction
performance.

Warning: The traction grade

assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
