WHEELS AND TIRES
566Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY REQUIRE-
MENTS IN ADDITION TO THESE GRADES.
Quality grades can be found, where applica-
ble, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment 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 many depart significantly from the norm due
to variation in driving habits, maintenance practi-
ces and differences in road characteristics and
climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test surfaces
of asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering (turn-
ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and exces-
sive temperature can lead to sudden tire failure.
The grade C corresponds to a minimum level of
performance that all passenger vehicle tires must
meet under the Federal Motor Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-infla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
tire failure.
