Consumer information
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 vehicle 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
Warning!
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.
