Overview of Tire Quality Grading
Standards
The Uniform Tire Quality Grading Standards
are U.S. government specifications. Their
purpose is to provide drivers with uniform
reliable
information
on tire performance data.
Tire manufacturers have to grade tires using
three performance factors: tread wear :,
tire traction ;, and heat resistance =. All
tires sold in North America are provided with
the corresponding quality grading markings on the sidewall of the tire, even though these
regulations do not apply to Canada.

The actual values for tires are vehicle-
specific and
may deviate from the values in
the illustration.
Where applicable, the tire grading
information can be found on the tire sidewall
between the tread shoulder and maximum
tire width.
For example: Tread wear Traction Temperature
200 AA A
All passenger car tires must conform to the
statutory 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
U.S. government 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 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 conditions. 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 traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent Uniform Tire Quality Grading Standards

Important safety notes G
WARNING
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling. Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation
of
fuel vapors are damaging to your
health.
