1995 PONTIAC GRAND-AM tire type

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
“overdriving” those conditions. But skids are always
possible.
The three types of skids correspond to your Pontiac’s
three control systems.
In the braking skid your wheels
aren’t rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid
too
much throttle causes the driving wheels to spin.
A cornering skid and an acceleration skid are best
handled by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration, or braking
(including engine braking by shifting to a lower gear).
Any sudden changes could cause the tires to slide. You
may not realize the surface is slippery until your vehicle
is skidding. Learn to recognize warning clues
-- such as
enough water, ice or packed snow
on the road to make a
“mirrored surface”
-- and slow down when you have
any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.

If you’re using a “dead-weight” hitch, the trailer tongue
(A) should weigh 10% of the total loaded trailer weight
(B).
If you have a “weight-distributing” hitch, the trailer
tongue
(A) should weigh 12% of the total loaded trailer
weight
(E).
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to
see if the weights are
proper. If they aren’t, you may be able to get them right
simply by moving some items around in the trailer.
Total Weight an Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the
recommended pressure for cold tires. You’ll find these
numbers on the Certification label at the
rear edge of the
driver’s door or see “Loading
Your Vehicle” in the
Index. Then be sure you don’t go over the
GVW limit
for your vehicle, including the weight of the trailer
tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going
by, and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
0
Will you have to make any holes in the body of your
vehicle when you install a trailer hitch? If you do,
then be sure
to seal the holes later when you remove
the hitch. If you don’t seal them, deadly carbon
monoxide
(CO) from your exhaust can get into your
vehicle (see “Carbon Monoxide” in the Index).
Dirt
and water can, too.
The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them. Use only a
frame-mounted hitch that does not attach to
$he
bumper.

Towing Your Vehicle
Try to have a GM dealer or a professional towing service
tow your Pontiac. The
usual towing equipment is:
(A) Sling-type tow truck (see Notice on the next page)
(B) Wheel-lift tow truck
(C) Car carrier
If your vehicle has been changed or modified since it
was factory-new
by adding aftermarket items like fog
lamps, aero skirting, (or special tires and wheels, these
instructions and illustrations may not be correct.
Before you
do anything, turn on the hazard warhing
flashers.
When you call, tell the towing service:
That your vehicle cannot be towed from the front or
rear with sling-type equipment,
as described later in
this section.
0 That your vehicle has front-wheel drive.
The make, model, and year of your vehicle.
0 Whether you can still move the shift lever.
0 If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want to
see them.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the rear
edge of the driver’s door shows the correct inflation
pressures for your tires, when they’re cold. “Cold”
means your vehicle has been sitting for at least three
hours or driven no more than a mile.
I NOTICE:
Don’t let anyone tell you that underinflation or
overinflation
is all right. It’s not. If your tires
don’t have enough
air (underinflation) you
can get:
0 Too much flexing
0 Too much heat
Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
(Continued)
1 NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get:
0 Unusual wear
0 Bad handling
0 Rough ride
0 Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell you the
pressure, especially if you have radial tires
-- which
may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping out dirt and
moisture.

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.

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.

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.
