1998 GMC SAVANA spare tire

Removing the Spare Tire and Tools
Your spare tire is stored underneath the rear of your
vehicle.
You will use the ratchet and extension to lower
the spare tire.
A flat rear tire reduces clearance to remove the spare
tire.
If there is less than 12 inches (30.48 cm) between
the ground and the rear bumper or any trailer hitch, jack
up the vehicle until the flat tire is off the ground. (See
“Removing the Flat Tire” and “Installing the Spare
Tire,” Steps
4 through 8, in this section.) Unless your vehicle has
a flat rear tire, do not remove
or restore a tire fromho
a storage position under the
vehicle while the vehicle is supported by a jack. Always
tighten
the tire fully against the underside of the vehicle
when restoring.
If you have a vehicle which was completed from a cab
and chassis, refer to the information from the body
supplierhnstaller.
The spare tire is a
full size tire, like the other tires on
your vehicle.
Remove the retaining wing bolt and lift it off the
mounting bracket. Set the jack and jacking equipment
near the flat tire.

Turn the ratchet to the left to lower the spare tire to the
ground. If you
are changing a flat rear tire and the
vehicle is already jacked up, use the jack handle and
extension to hook the cable. Then pull the spare from
beneath the vehicle. If the retainer pulls out, hook the
inside
of the wheel and pull the spare tire out from under
the vehicle.
When the tire has been lowered, tilt the retainer at the
end of the cable and pull it through the wheel opening.
I NOTICE: I
To help avoid vehicle damage, do not drive
vehicle before the cable is restored.

5. Raise the vehicle by rotating the ratchet to the right.
Make sure the
UP mark faces you. Raise the vehicle
far enough off the ground
so there is enough room
for the spare tire to fit.
6. Remove all the wheel
nuts, and take
off the
flat tire.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.

I A CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere as soon as
you can and have
the nuts tightened with a torque wrench
to
140 lb-ft (190 Nom).
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. Put
the wheel cover back
on, if you have one.
Remove any wheel blocks.
Remember that the jack, jacking equipment and tire
must be properly stored in their original storage
position before you begin driving again. The next
part will show you how.

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.

Inflation -- Tire Pressure
The Certificationflire label, which is 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
1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not. If your tires
don’t
hav.2 enough air (underinflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
0 Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
Check your tires once
a month or more. Also, check the
tire pressure
of the spare tire.

’
A CAUTION:
If you operate your vehicle with a tire that is
badly underinflated, the tire can overheat. An
overheated tire can lose air suddenly or catch
fire. You or others could be injured. Be sure all
tires (including the spare) are properly inflated.
Buying New Tires
To find out what kind and size of tires you need, look at
the Certificationmire 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.
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.

I A CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly, causing a crash. Use only radial-ply
tires with the wheels 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.
