wheel alignment OLDSMOBILE SILHOUETTE 1998 Owners Manual

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon
as possible and check
wheel alignment. Also crheck for damaged tires or
wheels.
See “When It’s ‘Time for New Tires”
and “Wheel Replacement” later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.

When rotating your tires, always use the correct rotation
pattern shown here. Don’t
include the compact spare tire
in your
tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
CertificatiodTire label. Make certain that all wheel
nuts are properly tightened. See “Wheel Nut Torque”
in the Index.
Rust or dirt on
a wheel, or on the parts to which
it is fastened, can make 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 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. (See
“Changing
a Flat Tire” in the Index.)

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 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
retailer if any
of these conditions exist.
Your retailer 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
Oldsmobile model.
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.
NOTICE:
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.
See “Changing
a Flat Tire” in the Index for more
information.
