Vehicle Care 357
Replace the tire if:
.The indicators at three or more
places around the tire can be seen.
.There is cord or fabric showing
through the tire's rubber.
.The tread or sidewall is cracked, cut,
or snagged deep enough to show
cord or fabric.
.The tire has a bump, bulge, or split.
.The tire has a puncture, cut, or other
damage that cannot be repaired well
because of the size or location of the
damage.
Tire Rotation
Tires should be rotated according to the
interval listed in the maintenance
schedule. SeeMaintenance Schedule
0 394.
Tires are rotated to achieve a more
uniform wear for all tires. The first
rotation is the most important.
Anytime unusual wear is noticed, rotate
the tires as soon as possible, check for
proper tire inflation pressure, and check for damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel alignment.
See
When It Is Time for New Tires
0 359 and
Wheel Replacement 0362.
If the full-size spare tire is part of the
tire rotation, make sure the tire rotated
into the spare position is stored
securely. Push, pull, and then try to
rotate or turn the tire. If it moves, use
the wheel wrench/hoist shaft to tighten
the cable. See Tire Changing0365.
Use this rotation pattern when rotating
the tires if the vehicle has single rear
wheels.
Dual Tire Rotation
When the vehicle is new, or whenever a
wheel, wheel bolt, or wheel nut is
replaced or serviced, check the wheel
nut torque after 160, 1 600, and
10 000 km (100, 1,000, and 6,000 mi) of
driving. For proper torque and wheel
nut tightening information, see “Wheel
Nut Torque” underCapacities and
Specifications 0402 and “Removing the
Flat Tire and Installing the Spare Tire”
under Tire Changing 0365.
The outer tire on a dual wheel setup
generally wears faster than the inner
tire. Tires last longer and wear more
evenly if they are rotated. See Tire
Inspection 0356 and
Tire Rotation 0357. Also see
Maintenance Schedule 0394.

If equipped with a spare tire cable,
reattach the clip to the frame
attachment bracket. Note that there may
be slack in the cable.
Repeat this tightness check procedure
when checking the spare tire pressure
according to the scheduled maintenance
information or any time the spare tire is
handled due to service of other
components.Correctly Stored
Incorrectly Stored
10. Reinstall the spare tire lock, if the vehicle has one. Return the jack and tools to their original
location in the vehicle. See
“Removing the
Spare Tire and Tools.”
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
0 350 and
Vehicle Load Limits 0210 for information
regarding proper tire inflation and loading
the vehicle. For instructions on how to
remove, install, or store a spare tire, see Tire
Changing 0365.
After installing the spare tire on the vehicle,
stop as soon as possible and check that the
spare is correctly inflated. The spare tire is
made to perform well at speeds up to
112 km/h (70 MPH) at the recommended
inflation pressure, so you can finish
your trip.
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 the
spare tire and its wheel together.

General Information
Your vehicle is an important investment.
This section describes the required
maintenance for the vehicle. Follow this
schedule to help protect against major repair
expenses resulting from neglect or
inadequate maintenance. It may also help to
maintain the value of the vehicle if it is
sold. It is the responsibility of the owner to
have all required maintenance performed.
Your dealer has trained technicians who can
perform required maintenance using genuine
replacement parts. They have up-to-date
tools and equipment for fast and accurate
diagnostics. Many dealers have extended
evening and Saturday hours, courtesy
transportation, and online scheduling to
assist with service needs.
Your dealer recognizes the importance of
providing competitively priced maintenance
and repair services. With trained technicians,
the dealer is the place for routine
maintenance such as oil changes and tire
rotations and additional maintenance items
like tires, brakes, batteries, and wiper blades.
Caution
Damage caused by improper maintenance
can lead to costly repairs and may not be
covered by the vehicle warranty.
Maintenance intervals, checks,
inspections, recommended fluids, and
lubricants are important to keep the
vehicle in good working condition.
Do not have chemical flushes that are not
approved by GM performed on the
vehicle. The use of flushes, solvents,
cleaners, or lubricants that are not
approved by GM could damage the
vehicle, requiring expensive repairs that
are not covered by the vehicle warranty.
The Tire Rotation and Required Services are
the responsibility of the vehicle owner. It is
recommended to have your dealer perform
these services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to keep
the vehicle in good working condition,
improves fuel economy, and reduces vehicle
emissions.
