This has been prepared as required of all manufactures 
of passenger cars under Title 49, Code of U.S. Federal 
Regulations, Part 575 pursuant to the “National Traffic 
and Motor Vehicle Safety Act of 1966”.
Uniform tire quality grading
Quality grades can be found where applicable on the 
tire sidewall between tread shoulder and maximum 
section width. For example:
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 
conditions on a specified government test course. For 
example, a tire graded 150 would wear one and one-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, and may depart significantly from the norm due to 
variations in driving habits, service practices and 
differences in road characteristics and climate.
Traction
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 performance.
Tread wear 200 Traction AA Temperature A
Wa r n i n g !
The traction grade assigned to this tire is based on 
straightahead braking traction tests, and does not 
include acceleration, cornering, hydroplaning, or 
peak traction characteristics.

Tempera t u re
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 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 represent higher levels of performance on the 
laboratory test wheel than the minimum required by 
law.
Wa r n i n g !
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 excessive heat build up 
and possible tire failure.
