DEPARTMENT OF TRANSPORTATION UNIFORM TIRE QUALITY
GRADES
The following tire grading categories were established by the National
Highway Traffic Safety Administration. The specific grade rating assigned by
the tire's manufacturer in each category is shown on the sidewall of the tires
on your vehicle.
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 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 Grades

The Traction grades, from highest to lowest, are AA, A, B, and C. These
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.
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.
