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.
Mixing tires could cause you to lose control while driving. If yuu
mix tires of different sizes or types (radial and bias-belted
tires), the vehicle may
not handle properly, and you could hpve a
.. crash. Be sure to use the same size and type tires on all four
wheels.
It's all right to drive with your compact spare, though. It was
' developed for use on your vehicle.

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.

Page 307 of 395

Downloaded from www.Manualslib.com manuals search engine 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 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 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.

Downloaded from www.Manualslib.com manuals search engine 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 Cadillac
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
Cadillac 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.

Tire Chains
NOTICE:
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 front 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.

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 Cadillac, 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:

CADILLAC
Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or
leather with a clean, damp cloth.
Your Cadillac 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.
Clean up stains as soon as you can -- before they set.
0 Use a clean cloth or sponge, and change to a clean area often. A soft
brush may be used if stains are stubborn.
0 Use solvent-type cleaners in a well-ventilated area only. If you use
them, don’t saturate the stained area.
0 If a ring forms after spot cleaning, clean the entire area immediately or
it will set.

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.

NOTICE:
Be careful. A blow dryer may scorch the fabric.
0 Wipe with a clean cloth.
Using Solvent-Qpe 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 a
blow dryer to help prevent a cleaning ring. (See the previous
NOTICE.)
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 and
asphalt.
0 Carefully scrape off excess stain.
0 Follow the solvent-type instructions described earlier.
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 careful,
because the cleaner will dissolve them
and may cause them to spread.
