Inf Infor ormation on tir mation on tire q e quality gr uality grades ades
According to the requirements of the U.S. Depart-
ment of Transportation's "Uniform Tire Quality
Grading Standards" tire manufacturers must grade
their tires using the following three performance
factors:
1
Tread wear grade
2
Traction grade
3
Temperature grade

This grading is not legally prescribed for Can-
ada, but speci ed in most cases anyway.
TTrread w ead wear gr ear grade ade
The tread wear grade is a comparative grading
based on tread wear grade tests conducted under
controlled conditions on a speci ed U.S. Depart-
ment of Transportation test track. For example, a
tire graded 150 would wear one and one-half times
as well on the government test track as a tire gra-
ded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart signi cantly from the norm due to var-
iations in driving habits, service practices and dif-
ferences in road characteristics and climate condi-
tions.

DDAN ANGER GER Risk of accident due to inade-
quate traction
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include either acceleration, cor-
nering, hydroplaning or peak traction charac-
teristics.

Always adapt your driving style and drive
at a speed to suit the prevailing tra c
and weather conditions.
