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.
You need a new tire if
0 You can see the indicators at three or more places
around the tire.
0 YOU can see cord or fabric showing through the tire’s
rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way,
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

I
It’s all right to drive with your compact spar
though.
It was developed for use on Your vehicl
The following information relates to the system
developed by the- United
States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction
md 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
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
overl'oaded. 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
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.

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. ~~~

Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed space.
When you
use anything from a container to clean your
Pontiac, be sure to follow the manufacturer’s warnings
and instructions. And always open your doors or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:

Cleaning the Inside of Your Pontiac
Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl or leather with a clean, damp cloth.
Your Pontiac dealer has two GM cleaners, a
solvent-type spot lifter and a foam-type powdered
cleaner. They will clean normal spots and stains very
well.
Do not use them on vinyl or leather.
Here are some cleaning tips:
Always read the instructions on the cleaner label.
0 Clean up stains as soon as you can -- before they set.
Use a clean cloth or sponge, and change to a clean area
often. A soft brush may be used if stains are stubborn.
Use solvent-type cleaners in a well-ventilated area
only. If you use them, don’t saturate the stained area.
If a ring forms after spot cleaning, clean the entire
area immediately or it will set.

Vacuum and brush the area to remove any loose dirt.
Always clean a whole trim panel or section. Mask
surrounding
trim along stitch or welt lines.
Mix Multi-Purpose Powdered Cleaner following the
directions on the container label.
Use suds only and apply with a clean sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.
Rinse the section with a clean, wet sponge.
Wipe
off what’s left with a slightly damp paper towel
or cloth.
Then dry it immediately with a blow dryer or a heat
lamp.
NOTICE:
Be careful. A blow dryer may scorch the fabric. ~~
0 Wipe with
a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean
off better with just
water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure and clean cloths (preferably
cheesecloth). Cleaning should start at the outside of
the stain, “feathering” toward the center. Keep
changing to a clean section of the cloth.
When you clean a stain from fabric, immediately dry
the area with a blow dryer to help prevent a cleaning
ring. (See the previous NOTICE.)
