1997 CHEVROLET EXPRESS spare wheel

Downloaded from www.Manualslib.com manuals search engine The ratchet has a DOWN side and an UP side.
Attach the ratchet, with the
DOWN side facing you, to
the extension. The extension has a socket end and
a flat
chisel end.
Put the flat end
of the extension on an angle through the
hole in the rear door frame, above the bumper. Be sure
the flat end connects into the hoist shaft. Turn the ratchet counterclockwise
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.

Spare Tire
1. With the DOWN side facing you, use the ratchet and
socket
to loosen all the wheel nuts. Don’t remove
them
yet.
2. The jack has a bolt on the end. Attach the socket end
of the extension to thejack bolt.
Attach
the ratchet to the extension with the UP side
facing
you.

r
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even make the vehicle fall.
To avoid personal injury and
vehicle damage, be sure
to fit the jack lift head into
the proper location before raising your vehicle.
5. Raise the vehicle by rotating the ratchet clockwise.
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.

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.
1. Put the tire on the ground at the rear of the vehicle,
with the valve stem pointed down.
2. Pull the retaining bar through the center of the
wheel, making sure
it is properly attached.

Downloaded from www.Manualslib.com manuals search engine Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel
nut torque
after
100, 1,000 and 6,000 miles ( 160, 1 600 and
10 000 km) of driving. For proper torque, see “Wheel
Nut Torque’’ in
the Index.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically.
If you’re going to be doing a lot
of driving on
high-crown roads, you can reduce tire wear by adding
5 psi (35 kPa) to the tire pressure in the outer tires. Be
sure
to return to the recommended pressures when no
longer driving under those conditions. See “Changing a
Flat Tire” in the Index for more information.
A CAUTION:
Buying New Tires
To find out what kind and size of tires you need, look at
the Certificationrnire 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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.

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.
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.
