Warning (Continued)
.Needless damage from road
hazards
The Tire and Loading Information label
on the vehicle indicates the original
equipment tires and the correct cold
tire inflation pressures. The
recommended pressure is the minimum
air pressure needed to support the
vehicle's maximum load carrying
capacity.
For additional information regarding
how much weight the vehicle can carry,
and an example of the Tire and Loading
Information label, see Vehicle Load
Limits 0193. How the vehicle is loaded
affects vehicle handling and ride
comfort. Never load the vehicle with
more weight than it was designed to
carry.
When to Check
Check the pressure of the tires once a
month or more. Do not forget the spare, if the vehicle
has one. See
Full-Size Spare Tire 0374
for additional information.
How to Check
Use a good quality pocket-type gauge
to check tire pressure. Proper tire
inflation cannot be determined by
looking at the tire. Check the tire
inflation pressure when the tires are
cold, meaning the vehicle has not been
driven for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the tire
valve stem. Press the tire gauge firmly
onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the Tire and Loading
Information label, no further adjustment
is necessary. If the inflation pressure is
low, add air until the recommended
pressure is reached. If the inflation
pressure is high, press on the metal
stem in the center of the tire valve to
release air. Re-check the tire pressure with the tire
gauge.
Put the valve caps back on the valve
stems to keep out dirt and moisture.
Use only valve caps designed for the
vehicle by GM. TPMS sensors could be
damaged and would not be covered by
the vehicle warranty.
Tire Pressure for High-Speed
Operation
{Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts additional
strain on tires. Sustained high-speed
driving causes excessive heat buildup and
can cause sudden tire failure. This could
cause a crash, and you or others could be
killed. Some high-speed rated tires require
inflation pressure adjustment for
high-speed operation. When speed limits
and road conditions allow the vehicle to
be driven at high speeds, make sure the
tires are rated for high-speed operation,

Vehicle Care 357
Lightly coat the inner diameter of the
wheel hub opening with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or rust
build-up.
{Warning
Do not apply grease to the wheel
mounting surface, wheel conical
seats, or the wheel nuts or bolts.
Grease applied to these areas could
cause a wheel to become loose or
come off, resulting in a crash.
When It Is Time for New Tires
Factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road
conditions affect the wear rate of the tires.
Treadwear indicators are one way to tell
when it is time for new tires. Treadwear
indicators appear when the tires have only
1.6 mm (1/16 in) or less of tread remaining.
See Tire Inspection 0355 and
Tire Rotation 0356.
The rubber in tires ages over time. This also
applies to the spare tire, if the vehicle has
one, even if it is never used. Multiple factors
including temperatures, loading conditions,
and inflation pressure maintenance affect
how fast aging takes place. GM recommends
that tires, including the spare if equipped,
be replaced after six years, regardless of tread wear. To identify the age of a tire, use
the tire manufacture date, which is the last
four digits of the DOT Tire Identification
Number (TIN) molded into one side of the
tire sidewall. The last four digits of the TIN
indicate the tire manufactured date. The
first two digits represent the week and the
last two digits, the year. For example, the
third week of the year 2020 would have a
4-digit DOT date of 0320. Week 01 is the
first full week (Sunday through Saturday) of
each year.Vehicle Storage
Tires age when stored normally mounted on
a parked vehicle. Park a vehicle that will be
stored for at least a month in a cool, dry,
clean area away from direct sunlight to slow
aging. This area should be free of grease,
gasoline, or other substances that can
deteriorate rubber.
Parking for an extended period can cause
flat spots on the tires that may result in
vibrations while driving. When storing a
vehicle for at least a month, remove the
tires or raise the vehicle to reduce the
weight from the tires.

Caution (Continued)
slow down until it stops. Driving too fast
or spinning the wheels with chains on
will damage the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out while
driving, especially if the tires are maintained
properly. SeeTires0344. 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 tire service center repair or
replace the flat tire as soon as possible.
{Warning
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could be
badly injured or killed if the vehicle slips
off the jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire. If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a level
place, well off the road, if possible. Turn on
the hazard warning flashers. See
Hazard
Warning Flashers 0142.
If your vehicle is loaded at or near
maximum cargo capacity, it may be difficult
to fit the jack under the vehicle due to the
environment (shoulder slope, road debris,
etc.). Removal of some weight may improve
the ability to fit the jack under the vehicle
at the correct jacking location.
{Warning
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall causing injury or death. Find a
level place to change the tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the vehicle in P (Park).
3. Turn the vehicle off and do not restart the vehicle while it is raised.
4. Do not allow passengers to remain in the vehicle.

6. Repeat Steps 4 and 5 for the otherhexagon bolt.
7. Lift the spare tire cage (2) slightly andmanually disengage both hook ends (3).
For easier disengagement of the hook
ends, insert the chisel end of the wheel
wrench into one of the tubes (1) and
apply upward pressure while disengaging
the hook. Do this to both sides.
8. Lift the spare tire and remove it fromthe cage.
The cage will not lower completely to
the ground but will allow ample room to
remove the spare tire.
9. The spent road wheel will be stored in the rear of the vehicle. See “Storing a
Flat or Spare Tire and Tools.”
10. Lift the empty spare tire cage (2) and manually engage both hook ends, with
hook openings facing the rear of the
vehicle (3).
Ensure that both hook ends stay
engaged with the spare tire cage during
the raising process that follows. 11. Assemble the wheel wrench and wheel
wrench adapter as in Step 4.
12. Raise the empty spare tire carrier, turning the hexagon bolts clockwise until
each side begins to ratchet.
Ratcheting of both bolts indicates the
spare tire carrier has been raised to its
maximum, stowed position.
The spare tire carrier is properly stowed
when ratcheting has occurred on both
bolts, and the hook ends are engaged
and pulled taut from supporting the
weight of the cage.
13. Replace the hexagon bolt caps.
Removing the Flat Tire and Installing the
Spare Tire
1. If the wheel has a center cap that covers the lug nuts, place the chisel end of the
wheel wrench in each of the slots in the
cap, and gently pry it out.
2. Do a safety check before proceeding. See If a Tire Goes Flat 0362.
