Uniform tire quality grading
standards
This information indicates the relative
performance of passenger car tires in
the area of treadwear, traction, and
temperature resistance. This is to aid
the consumer in making an informed
choice in the purchase of tires.
Quality grades can be found where
applicable on the tire sidewall be-
tween tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Tem-
perature A
The quality grades apply to new pneu-
matic tires for use on passenger cars.
However, they do not apply to deep
tread, winter type snow tires, space-
saver or temporary use spare tires,
tires with nominal rim diameters of 12
inches or less, or to some limited pro-
duction tires.
All passenger car tires must confirm
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 con-
ditions 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 perfor-
mance of tires depends upon the ac-
tual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving hab-
its, service practices and differences
in road characteristics and climate.
¢ Traction AA, A, B, C
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 speci-
fied government test surfaces of as-
phalt and concrete. A tire marked C
may have poor traction performance.
