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 one and one-half (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
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.
