Uniform Tire Quality Grading
Quality grades can be found where applica-
ble on the tire sidewall between tread
shoulder and maximum section width.
E.g.: Treadwear 200; Traction AA; Tempera-
ture A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger vehicle tires must conform to
Federal Safety Requirements in addition to
these 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. E.g., a
tire graded 150 would wear one and one-
half, 1 g, times as well on the government
course as a tire graded 100. The relative
performance of tires depends upon the ac-
tual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices 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 to
stop on wet pavement as measured under
controlled conditions on specified govern-
ment test surfaces of asphalt and concrete.
A tire marked C may have poor traction per-
formance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
