Information About Uniform Tire
Quality Grading
E142542
Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA
Temperature A.
These Tire Quality Grades are
determined by standards that the
United States Department of
Transportation has set.
Tire Quality Grades apply to new
pneumatic passenger car tires. They
do not apply to deep tread,
winter-type snow tires, space-saver or
temporary use spare tires, light truck
or LT type tires, tires with nominal rim
diameters of 10 to 12 inches or limited

Tire quality grades: The U.S.
Department of Transportation requires
Ford Motor Company to give you the
following information about tire grades
exactly as the government has written
it.
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. For example, a tire graded
150 would wear 1 ½ times as well on
the government course as a tire
graded 100. The relative performance
of tires depends upon the actual
conditions 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 AA A B C
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.
