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 Treadwear
The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlledconditions 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 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
The traction grades, from highest to
lowest, are AA, A, B, and C. Those
grades represent the tire's ability tostop 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 onstraight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.

Temperature
The temperature grades are A (thehighest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlledconditions on a specified indoor
laboratory test wheel. Sustained high temperature can cause the materialof the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum required by law. Warning: The temperature grade for
this tire is established for a tire thatis properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading either separately or in combination, can
cause heat build-up and possible tire
failure.
