DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following describes the tire grading categories estab-
lished by the National highway Traffic Safety Adminis-
tration. The specific grade rating assigned by the tire's
manufacturer in each category is shown on the sidewall
of the tires on your car.
All Passenger Car Tires Must Conform 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 ex-
ample, a tire graded 150 would wear one and a half (1
1/2) 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, andmay depart significantly from the norm due to variations
in driving habits, service practices and differences in road
characteristics and climate.
Traction Grades
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 specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
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.
382 IF YOU NEED CONSUMER ASSISTANCE

Temperature Grades
The 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
excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance, which all
passenger car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B and A repre-
sent higher levels of performance on the laboratory test
wheel than the minimum required by law.WARNING!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
