Consumer information
Consumer information
The following text is published as required
of all manufacturers 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.Tread Wear
The tread wear 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 varia-
tions 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.

Warning!
G
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.
