Consumer Information
This has been prepared 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
Refer to the tire sidewall for the specific
tire grades for the tires with which this
vehicle is equipped.
All passenger car 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 (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 "A", "B", "C"
The traction grades, from highest to
lowest, are "A", "B" and "C" and they
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!
The traction grade assigned to this
tire is based on braking (straight
ahead) traction tests and does not
include cornering (turning) traction.
Temperature "A", "B", "C"
The temperature grades are "A" (the
highest). "B" and "C", representing the
tire's resistance to the generation of heat
and its ability .to dissipate heat when
tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire fail-
ure. The grade "C" corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109 Grades "B" and "A" represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
Warning!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause excessive
heat build up and possible tire
failure.
