Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash.(Continued)
Warning (Continued)
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and road
conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the front tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. See Tires
0 300. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there is ever a blowout, here
are a few tips about what to expect
and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized

{Warning
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
11. Reinstall the wheel nuts. Tighten each nut by hand until
the wheel is held against
the hub.
12. Lower the vehicle by turning the jack handle
counterclockwise.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when

Warning (Continued)
using accessory locking wheel
nuts. SeeCapacities and
Specifications 0366 for original
equipment wheel nut torque
specifications.
Caution
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. See
Capacities and Specifications
0 366 for the wheel nut torque
specification.13. Tighten the wheel nuts firmly in a crisscross sequence, as
shown.
14. Lower the jack all the way and remove the jack from under the
vehicle.
15. Tighten the wheel nuts firmly with the wheel wrench.
When reinstalling the wheel cover or
center cap on the full-size tire,
tighten all five plastic caps hand
snug with the aid of the wheel
wrench and tighten them with the
wheel wrench an additional
one-quarter of a turn.

compact spare, the cover or the
spare could be damaged.
Storing a Flat or Spare Tire
and Tools
{Warning
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could

the loop and pull the strap to
tighten it around the cargo
tie-down.
6. Route the hook end of the strap through the wheel.
7. Attach one end of the strap to a cargo tie-down in the rear of
the vehicle.
8. Route the strap through thewheel, as shown.
9. Attach the other end of the strap to the other cargo
tie-down in the rear of the
vehicle.
10. Tighten the strap

use only. Replace the compact
spare tire with a full-size tire as
soon as possible.
