Traction -- A, B, C The traction sades, from highest to lowesr. 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 per-fornmance. Warning: The traction grade assigned to this tire is based on braking (straight ahead)traction tests and does not include cornering (turning) traction. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or o excessive loading, either separately r in combination. can cause heat buildup and possible tire failure. 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. Scheduled wheel alignment and wheel balancing are not needed. However, if you notice unusual tire wear or your vehicle pulling one way or the other. the alipment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. 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 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. Wheel Replacement Replace any wheel that is bent. cracked, or badly rusted or corroded. 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 GM dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. 6-46

need to be reset.
If
you notice your vehicle
vibrating when driving
on

smooth road, your wheels
may
need to be rebalanced.
Wheel
Replacement
Replace any wheel that
is
bent. cracked, or badly rusted
or corroded.
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
GM
dealer
if
any
of
these
conditions exist.
Your dealer
will
