Tire chains won’t fit your compact spare. Using
them
will damage your vehicle and destroy the
chains too. Don’t use tire chains on your compact
spare.
If You’re Stuck: In Sand, Mud, Ice or
Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast.
The method known as
“rocking” can help
you get out when you’re stuck, but
you must use caution.

NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well
as the tires. If you spin the wheels
too fast while shifting your transmission back
and forth, you can destroy your transmission.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If your vehicle
has traction control, you should turn the system
off. (See
“Traction Control System” in the Index.) Then shift
back and forth between REVERSE (R) and
a forward
gear (or with a manual transmission, between FIRST
(1)
or SECOND (2) gear and REVERSE), spinning the
wheels as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transmission is in gear.
If that doesn’t
get you out after a few tries, you may need to be towed
out. If you do need to be towed out, see “Towing Your
Car” in the Index.

What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only,
and always clean the brake fluid
reservoir cap before removing it.
c,
NOTICE:
Don’t let someone put in the wrong kind of
fluid. For example, just a few drops of
mineral-based oil, such as engine oil, in
your brake system can damage brake
system parts
so badly that they’ll have to be
replaced.
Brake fluid can damage paint, so be careful
not to spill brake fluid on your vehicle.
If
you do, wash it off immediately. See
“Appearance Care” in the Index.
Brake Wear
Unless you have the four-wheel disc brake option, your
Pontiac has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched wanzing sound when the brake pads are
worn and new pads
are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you
are pushing on the brake pedal firmly).
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear is present, rotate your tires as soon as
possible and check wheel alignment. Also check 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.

If you don’t have P245/5OZR16 Goodyear Eagle GS-C
tires, use the rotation pattern shown above for your tires.

If you have P245/5OZR16 Goodyear Eagle GS-C tires,
they must roll
in a certain direction for the best overall
performance. The direction
is shown by an arrow on
both sidewalls. Because these tires are directional, they should be rotated as shown here. These tires should only
be moved from front to rear and rear to front on the
same side
of the vehicle. I I

After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the
Index.
When it’s Time for New Tires
One way to tell when it’s
time for new tires
is to
check the treadwear
indicators, which will
appear when your
tires have
only 1/16 inch (1.6
mm) or
less of tread remaining.

Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions
of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
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
€3 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.
These 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
6-53
ProCarManuals.com
Page 287 of 386

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
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
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.

NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometer/odometer calibration, headlamp
aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.
Used Replacement Wheels
Tire Chains
NOTICE:
If your Pontiac has P235/55R16, or P245/50ZR16
size tires, don’t use tire chains; they can dqpage
your vehicle.
If you have other tires, use tire chains only where
legal and only when you must. Use only
SAE
Class “S” type chains that are the proper size for
your tires. Install them on the rear tires and
tighten them as tightly
as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions.
If you can
hear the chains contacting your vehicle, stop and
retighten them.
If the contact continues, slow
down until
it stops. Driving too fast or spinning
the wheels with chains
on will damage your
vehicle.
