Tire Information
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 perfor-
mance according to Department of
Transportation (DOT) standards.
The following explains those grades.
Treadwear
The treadwear grade is a comparative
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 (1-1/2) times as well on the
government course as a tire graded
100. The relative performance of tires
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 differences in
road characteristics and climate.
Traction
The traction grades, from highest to
lowest, are A, B, and C, and they
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 as-
signed to this tire is based on braking
(straight ahead) traction tests and
does not include cornering (turning)
traction.
