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 production tires as defined in
Title 49 Code of Federal Regulations Part
575.104 (c)(2).
U.S. Department of Transportation 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 1½
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
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.
The traction grades, from highest to lowest
are AA, A, B, and C. The 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.
Temperature A B C
WARNING
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
