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.
