1993 PONTIAC GRAND-AM wheel

Traction-A, B, C
The traction grades, from highest to
lowest are:
A, B, and C. They represent
the tire’s ability to stop on wet pavement
as measured under controlled conditions
on specified government test surfaces of
asphalt and concrete.
A tire marked C
may have poor traction performance.
Warning: The traction grade assigned
to this tire is based on braking (straight-
ahead) 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.
Those grades are molded on the sidewalls of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles 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
Pontiac 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
Pontiac model.
CAUTION I
Using the wrong replacement
I. 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.

Used Replacement Wheels
Putting a used wheel on your
L vehicle is dangerous. You
I cs know how it’s been used or
how many miles it’s been driven. It
-mid fail suddenly and cause an
accident. If you have
to replace a
\wheel, use a
new GM original If your Pontiac has P195/70R14,
P195/65R15
or P205/55R16 size
tires, don’t use tire chains; they can
damage your vehicle.
If you have other tires, use tire
chains only when you must. Use
only
SAE Class “S” type chains
that are
the proper size for your
tires. Install them
on the front tires
and tighten them as tightly as
possible with the ends securely fastened. Drive slowlv and follow
r’
the chain manufacturer’s
instructions. If you can
h
chains contacting your v
stop and retighten them. If the
contact continues, slow down until
it stops. Driving too fast with
chains on will damage your vehicle.

dish or car washing (non-detergent)
soaps. Don’t use cleaning agents that
contain acid or abrasives. All cleaning
agents should be flushed promptly and
not allowed to dry on the surface, or
they could
stain. Dry the finish with a
soft, clean chamois or a 100% cotton
towel to avoid surface scratches and water spotting.
High pressure vehicle washes may cause
water to enter your vehicle.

Finish Care
Occasional waxing or mild polishing of
your Pontiac may be necessary to
remove residue from the paint finish.
You can get
GM approved cleaning
products from your dealer. (See the
Ida under Appearance Care.)
Your Pontiac has a “basecoat/
clearcoat” paint finish. The clearcoat
gives more depth and gloss to the
colored basecoat.
Aluminum Wheels
If your Pontiac has these, don’t use
chrome polish on them. Use wax after
you clean them.
Also, don’t use abrasive
cleaners or cleaning brushes on them-
you could damage the protective
coating.

WHAT SHOULD BE DONE I
Inspect the front and rear suspension and steering system for \
damaged, loose or missing parts,
signs
of wear, or lack of lubrication. Inspect the power steering lines and hoses for proper
hookup, binding, leaks, cracks, chafing, etc. Clean and then in\
spect the drive axle boot seals for damage, tears or leakage. Replace seals if necessary.
Inspect the complete exhaust system. Inspect the body near the \
exhaust system. Look for broken,
damaged, missing or out-of-position parts
as well as open seams, holes, loose connections, or
other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes
into the vehicle. See the
Idex under EnRine Exhaust.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed.
Inspect the complete system. Inspect brake lines and hoses for \
proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rot\
ors for surface condition. Also
inspect drum brake linings for wear and cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc. The parking brake is self-adjusting and no manual
adjustment is required,
You may need to have your brakes inspected more often if your driving
habits or conditions result in frequent braking.
NOTE:
A low brake fluid level can indicate worn disc brake pads which \
may need to be
serviced. Also, if the brake system warning light stays on or comes on, something may be wrong
with the brake system. See the
Index under Brake System Warning Light. If your anti-lock brake
system warning light stays on, comes on or flashes, something may be wrong with the anti-lock
brake system. See the
Index under Anti-Lock Brake System Warning Light.
