Downloaded from www.Manualslib.com manuals search engine When lt’s Time for New Tires
a
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
2/32 inch (1.6
mm) or less of tread
remaining.
You need a new tire if
You can see the indicators at three or more places around the tire.
You can see cord or fabric showing through the tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep enough to show
cord or fabric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t be re\
paired well
because of the
size or location of the damage.
Buying New Tires
To find out what kmd and size of tires you need, look at the
Certificatioflire label.
The tires installed on your vehicle when it was new had a Tire Performance
Criteria Specification (PC 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 thin\
gs during
normal service on your vehicle.
If your tires have an all-season tread
design, the TPC number will be followed by a
“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.

Downloaded from www.Manualslib.com manuals search engine Uniform Tire Quality Grading
The following information relates to the system developed by the Un\
ited
States National Highway Traffic Safety Administration which grade\
s tires
by treadwear, traction and temperature performance. (This applie\
s 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 gov\
ernment 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 var\
iations
in
driving habits, service practices and differences in road charac\
teristics and
climate.
Tractlon - A, 9, 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.
6-56

Downloaded from www.Manualslib.com manuals search engine Temperature -A, By 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 tes\
t wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to su\
dden 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, underinfla\
tion, 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. 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 GM 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.
6-57

Downloaded from www.Manualslib.com manuals search engine 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
GM model.
NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim,
bumper height, vehicle ground clearance, and tire or tire chain\
clearance to the body and chassis.

NOTICE:
If your vehicle has P235/75R15 or 31xlOSOR15LT/C size tires,
don’t use tire chains; they can damage your vehicle.
If you have other size 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 drive axle
tires (four-wheel-drive vehicles can use chains on both axles)
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 with chains on will damage your
vehicle.
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 vehicle, be sure to
follow the manufacturer’s warnings and instructions. And always open your\

doors or windows when you’re cleaning the inside.

Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or
leather with a clean, damp cloth.
Your vehicle dealer has two GM cleaners, a solvent-type spot lifter and a
foam-type powdered cleaner. They will clean normal spots and st\
ains very well.
Do not use them on vinyl or leather.
Here
are some cleaning tips:
0 Always read the instructions on the cleaner label.
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

0 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.
0 Rinse the section with a clean, wet sponge.
0 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 with a hair dryer or heat lamp. You could scorch the
fabric.
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.
0 When you clean a stain from fabric, immediately dry the area with an
air hose, hair dryer, or heat lamp to help prevent a cleaning ring. (See
the previous NOTICE.)

Downloaded from www.Manualslib.com manuals search engine Fabric Protection
Your vehicle has upholstery and carpet that has been treated with
Scotchgard
TM Fabric Protector, a 3M product. Scotchgard TM protects fabrics
by repelling oil and water, which are the carriers of most stains. Even with
this protection, you still need to clean your upholstery and carpet often to
keep it looking new.
Further information on cleaning is available by calling
1-800433-3296 (in
Minnesota,
1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Such as grease, oil, butter, margarine, shoe polish, coffee with cream, \
chewing gum, cosmetic creams, vegetable oils, wax crayon, tar a\
nd asphalt.
Carefully scrape off excess stain.
Follow the solvent-type instructions described earlier.
0 Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon as possible. Be c\
areful,
because the cleaner will dissolve them and may cause them to spread.
Non-Greasy Stains
Such as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine,
vomit, urine and blood.
