1993 BUICK CENTURY wheel bolts

I A CAUTION:
Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come
off and cause an accident. When you
change a wheel, remove any rust or
dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use
a cloth
or a paper towel to do this; but be sure
to use
a scraper or wire brush later, if you need to, to
get all the rust or
dirt off. ’. : .a.

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.
Those grades are molded on the sidewalls of'passenger
car tires.
While the tires available as standard or optional
equipment on General Motors vehicIes 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
out, 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.
