the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo. Never exceed the
GVWR for your vehicle, or the Gross Axle Weight Rating (GAWR) for
either the front or rear axle.

TIRES
We don’t make tires. Your new vehicle comes with high quality tires made
by a leading tire manufacturer. These tires are warranted by the tire
manufacturers and their warranties are delivered with
every new Cadillac.
If your spare tire is a different brand than your road tires, you will have a
tire warranty folder from each of these manufacturers.

i --
Poorly maintained and improperly used tires are dangerous.
Overloading your tires can cause overheating as a result of
I
too much friction. You could have an air-out and a serious
accident. See “”Loading Your Vehicle” in the Index.
0 Underinflated tires pose the same danger as overloaded
tires. The resulting accident could cause serious injury.
Check all tires frequently
to maintain the recommended
pressure. Tire pressure should
be checked when your tires
are cold.
I
I Overinflated tires are more likely to be cut, punctured, or
broken by
a sudden impact, such as when you hit a pothole.
Keep tires at the recornmended pressure.
@ Worn, old tires can cause accidents. If your tread is badly
worn, or if your tires have been damaged, replace them.

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. 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.
Your tire pressures are:
Front and rear - 30 psi (210 kPa)
Optional Limousine packages:
Front and rear - 35 psi (241 kPa)
Recommended tire size is:
0 P235/70R15 (Front and rear)

To make your tires last longer, have them inspected and rotated at the
mileages recommended in the Maintenance Schedule. See “Scheduled
- Maintenance Services” in the Index. Use this rotation pattern.

After the tires have been rotated, adjust the front and rear inflation
pressure as shown on the Tire-Loading Information label. Make certain
that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the
Index.
A CAUTION:
Rust or dirt on a wheel, or on the parts to which it is fastened,
can make wheel nuts become loose after a time. The wheel could
come
off and cause an accident. When you change a wheel,
remove any rust
or dirt from places where the wheel attaches to
the vehicle. In an emergency, you can use
a cloth or a paper towel
to do this; but be sure to use a scraper
or wire brush later, if you
need to, to get all the rust
or dirt off. (See “Changing a Flat Tire”
in the Index.)

Downloaded from www.Manualslib.com manuals search engine When It’s Time for New Tires
You need a new tire if 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 can see the indicators at three 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.
0 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 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.
A CAUTION:
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.
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 limited use
on your vehicle.

Ungorm Tire Quality Grading
The following information relates to the system developed by the United'
States National Highway Traffic Safety Administration which grades tires
I
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 !
-and concrete. A tire marked C may have poor traction performance. I I
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

. .J
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 overloaded. Excessive speed, underinflation,
or excessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure.
Those 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.
