DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle meet all
U.S. Federal Safety Requirements.
A l l tires are also graded for
treadwear, traction, and temperature
performance 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 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 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 A A , 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.
