on a specified government test course. For
example, a tire graded 150 would wear
one and a 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
iowest are:
A, B, and C. 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
. . .208
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 failure. 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 heat buiidup
and possible tire failure.
These grades are molded on the sidewalls
of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General Motors
performance standards and have been
approved for use on General Motors
vehicles. All passenger type
(P Metric)
tires must conform to Federal safety
requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to
give you the longest tire life and best
overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear or your
vehicle pulling one way or
the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels may need to be rebalanced.
Wheel- Replacement - . -
Replace any wheel that is bent, cracked or
badly rusted. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can sometimes
be repaired). See your Chevrolet dealer
if any of these conditions exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted
the same way as
the one it replaces.
