1996 GMC SIERRA wheel bolts

4. Remove all the wheel
nuts and take off the
flat tire.
5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel. 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.
I A CAUTIO^:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.

Tempera 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
GM 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.
If you need to replace any
of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure
to have the
right wheel, wheel bolts and wheel nuts for your vehicle.

I
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose. control.
You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts for
replacement.

The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.

Whenever a wheel, wheel bolt or wheel nut is replaced
on a dual wheel setup, check the wheel
nut torque after
100,
1,000 and 6,000 miles (160, 1 600 and 10 000 km)
of driving. For proper torque, see “Wheel Nut Torque”
in
the Index.
See “Changing a Flat Tire” in the Index for
more information.
