Warning: The traction grade assigned to this tire is based
on braking (straightahead) 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 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 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.
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
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
Buick 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.
