in the
vehicle's
frame nearest the flat tire.
Put the compact spare tire near
you.
4. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle
far enough off the
ground
for the spare tire to fit under the vehicle.

NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
Don’t
try to put a wheel cover on your compact spare
tire. It won’t
fit. Store the wheel cover in the trunk until
you have the flat tire repaired or replaced.
NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare,
you could damage the cover or the spare.
Storing the Flat Tire and Tools
. ..
A CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In
a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
After you’ve put the compact spare tire on your vehicle,
you’ll need to store
the flat tire in your trunk. Use the
following procedure
to secure the flat tire in the trunk.
Put the
flat tire in the trunk so the side that faces out
when it is on the vehicle is facing down. The full-size
tire will not
fit down into the well. Place it so the front is
in the well and the rear is out of the well.

The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as
soon as you
can. See the storage instructions label to replace your
compact spare into your trunk properly.
Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehtcle
was new, it can lose air after a time. Check
the inflation pressure regularly.
It should be 60 psi
(420 Wa).
After installing the compact spare on your vehicle, you
should stop
as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at posted speed limits for distances up to
3,000 miles (5 000 km), so you can
finish your trip and have your full-size tire repaired or
replaced where you want. Of course, it’s best to replace your spare with
a full-size tire as soon as you can. Your
spare will last longer and be in
good shape in case you
need it again.

We don’t make tires. Your new Cadillac comes with
high-quality tires made by a leading tire manufacturer.
If you ever have questions about your tire warranty and
where to obtain service, see your Cadillac Warranty
booklet for details.
A CAUTION:
Poorly maintained and improperly used tires are
dangerous.
Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle’’ in
the Index.
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.
CAUTION: (Continued)
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 recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
See “Inflation
-- Tire Pressure’’ in this section
for inflation pressure adjustment for higher
speed driving.
Inflation -- Tire Pressure
The Tire-Loading Information label which is located 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.
If you’ll be driving at speeds higher than
100 mph
(160 km/h) where it is legal, raise the cold inflation
pressure
of each tire to 35 psi (240 Wa). When you end
this very high-speed driving, reduce the cold inflation

?ressures to those listed on the Tire-Loading [nformation label.
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:
, Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Needless damage from road hazards.
i Rough ride
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. 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.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 OOO to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon
as
possible and check wheel alignment. Also check for
damaged tires
or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later
in this section for
more information.

The purpose of regular rotation is to achieve more
uniform wear
for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services”
in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating
your tires, always use the correct rotation
pattern
shown here.
Don’t include the compact spare
tire in your tire rotation. After
the tires have been rotated, adjust the front and
rear inflation pressures 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 I
sure to use a scraper or wire brush later, if you
need to, to get
all the rust or dirt off. (See I
“Changing a Flat Tire” in the Index.)

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.
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
A and B 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.
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.
A CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose
air and make you
lose control. You could have
a collision in which
you or others could be injured.
Always use
the correct wheel, wheel bolts and wheel nuts
for replacement.
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.
See “Changing
a Flat Tire” in the Index for
more information.
