1997 PONTIAC PONTIAC 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 is best handled by easing your foot off
the accelerator pedal.
If you have the Trac System, remember: It helps avoid
only the acceleration skid. If
you do not have the Trac System, or if the system is
off, then an acceleration skid is also 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 slud
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 weight-carrying hitch, the trailer
tongue
(A) should weigh 10 percent of the total loaded
trailer weight
(€3). If you have a weight-distributing
hitch, the trailer tongue (A) should weigh
12 percent 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 on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper
limit for cold tires. You’ll find these numbers
on the
Tire-Loading Information label, found on the inside of
the
trunk lid, 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:
Your vehicle may have nonmetallic, composite
bumpers. The bumpers on your vehicle are not
intended
for bitches. DO not attach rental hitches
or other bumper-type hitches to them. Use only
a frame-mounted hitch that does not attach to
the bumper.

Towing Your Vehicle
Try to have a Pontiac dealer or a professional towing
service tow your vehicle.
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
warning flashers.
When you call, tell the towing service:
That your vehicle cannot be towed from the front
with sling
type equipment.
0 That your vehicle has front-wheel drive.
0 The make, model, and year of your vehicle.
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.
r
I
To help avoid injury to you or others:
0 Never let passengers ride in a vehicle that is
Never tow faster than safe or posted speeds.
Never tow with damaged parts not fully secured.
Never get under your vehicle after it has
been lifted by the tow truck.
Always secure the vehicle on each side with
separate safety chains when towing it.
Never use J-hooks. Use T-hooks instead.

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 the following:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
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 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can't tell if your tires
are properly inflated
simply
by looking at them, Radial tires may look
properly inflated even when they're underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks
by keeping out dirt and moisture.

g 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 sarne 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. Reset Tire
Inflation Monitor
(TIM).
I
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted
tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires of different sizes may also cause
damage to your vehicle.
Be sure to use the same
size and type tires
on all wheels.
It’s all right to drive with your compact spare,
though. It was developed for use on your vehicle.

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.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system
does not apply
to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters
of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
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, and 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 (straightahead) traction tests and
does not include cornering '(turning) traction.
