with as little exposure to light as possible.
Protect tires from contact with oil, grease
and fuels.
All passenger car tires must conform to
federal safety requirements in addition to
these grades.

tires. The intense jet of water can result in
damage to the tire.
Always replace a damaged tire.
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
U.S. 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
G 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.
The Uniform Tire Quality Grading is a U.S.
Government requirement designed to give
drivers consistent and reliable information
regarding tire performance. Tire
manufacturers are required to grade tires
based on three performance factors:
treadwear:, traction;, and temperature
resistance=. Although not a Government of
Canada requirement, all tires made for sale in
North America have these grades branded on
the sidewall.
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.
i For illustration purposes only. Actual data
on tires are specific to each vehicle and
may vary from data shown in above
illustration.
G Warning!
If ice has formed on the road, tire traction will
be substantially reduced. Under such weather
conditions, drive, steer and brake with
extreme caution.
Quality grades can be found, where
applicable, on the tire sidewall between tread
shoulder and maximum section width. For
