1993 BUICK ROADMASTER wheel

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 .I 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 how 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 Buick
model.
/! CA-TION:
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.

Aluminum Wheels
If your Buick has these, don’t use chrome polish on
them.
Use wax after you clean them. Also, don’t use
abrasive cleaners or cleaning brushps on them - you
could damaee the proutive caating.
Your Buick dealer has a
GM White Sidewall Tire
Cleaner. You can use
a stiff brush with it.
Weatherstrips
These are places where glass-or metal meets rubber.
Silicone grease there will make them last longer, seal
better, and not squeak. Apply silicone grease with
a
clean cloth at least every si%. mmtk. .-
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair
shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.

Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
damage your vehicle’s finish if they remain -on painted
surfaces. Use cleaners that are marked safe for painted
