before raising the vehicle.
5. Remove all of the wheel nuts.
6. Take off the flat tire. 7. Remove any rust or dirt from
the wheel bolts, mounting
surfaces, and spare wheel.
{ WarningRust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
(Continued) Warning (Continued) towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
8. Put the wheel nuts back on
with the rounded end of the
nuts toward the wheel after
mounting the spare tire.
{ WarningNever use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.

hand. Then use the wheel
wrench to tighten the nuts until
the wheel is held against
the hub.

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
(Continued) Warning (Continued) using accessory locking wheel
nuts. See Capacities and
Specifications 0 384 for original
equipment wheel nut torque
specifications.
CautionImproperly 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
0 384 for the wheel nut torque
specification.
When reinstalling the regular wheel
and tire, also reinstall either the
center cap or the bolt-on hub cap,
depending on which one the
vehicle has. .
For center caps, line up the tab
on the center cap with the slot in
the wheel. The cap only goes in
one way. Place the cap on the
wheel and press until it snaps
into place.
.
For bolt-on hub caps, line up the
plastic nut caps with the wheel
nuts and tighten clockwise by
hand to get them started. Then
tighten with the wheel wrench
until snug.

Full-Size Spare Tire If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly.
See Tire Pressure 0 327 and
Vehicle Load Limits 0 200 . For

GMC Yukon/Yukon XL/Denali Owner Manual (GMNA-Localizing-U.S./
Canada/Mexico-11349262) - 2018 - crc - 6/20/17
Vehicle Care 351instructions on how to remove,
install, or store a spare tire, see Tire
Changing 0 342 .
If equipped with a temporary use
full-size spare tire, it is indicated on
the tire sidewall. See Tire Sidewall
Labeling 0 322 . This spare tire
should not be driven on over
112 km/h (70 mph), or 88 km/h
(55 mph) when pulling a trailer, at
the proper inflation pressure. Repair
and replace the road tire as soon as
it is convenient, and stow the spare
tire for future use.
CautionIf the vehicle has four-wheel drive
and a different size spare tire is
installed, do not drive in
four-wheel drive until the flat tire
is repaired and/or replaced. The
vehicle could be damaged and
the repairs would not be covered
by the warranty. Never use
four-wheel drive when a different
size spare tire is installed on the
vehicle. The vehicle may have a different
size spare tire than the road tires
originally installed on the vehicle.
This spare tire was developed for
use on this vehicle, so it is all right
to drive on it. If the vehicle has
four-wheel drive and a different size
spare tire is installed, drive only in
two-wheel drive.
After installing the spare tire on the
vehicle, stop as soon as possible
and check that the spare tire is
correctly inflated.
Have the damaged or flat road tire
repaired or replaced and installed
back onto the vehicle as soon as
possible so the spare tire will be
available in case it is needed again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep your spare tire and its
wheel together. If the vehicle has a
spare tire that does not match the
original road tires and wheels in size
and type, do not include the spare in
the tire rotation. Jump Starting Jump Starting - North
America For more information about the
vehicle battery, see Battery - North
America 0 298 .
If the vehicle's battery has run
down, you may want to use another
vehicle and some jumper cables to
start your vehicle. Be sure to use
the following steps to do it safely.
