Dual Tire Rotation - GMC 2012 Sierra Denali Owner's Manual

10-64 Vehicle Care
WARNING
Rust 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
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Reset the Tire Pressure Monitor
System (TPMS), if the vehicle
has one. See Tire Pressure
Monitor Operation on
page 10 58.
Check that the spare tire, if the
vehicle has one, is stored
properly. Push, pull, and then try
to rotate or turn the tire. If it
moves, tighten the cable. See
Storing a Flat or Spare Tire and
Tools under Tire Changing on
page 10 73.

Dual Tire Rotation

When the vehicle is new,
or whenever a wheel, wheel
bolt, or wheel nut is replaced,
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
Removing the Spare Tire and
Tools under Tire Changing on
page 10 73.
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 on page 10 62 and
Tire Rotation on page 10 62. Also
see Maintenance Schedule on
page 11 3.
WARNING
If the vehicle is operated with a
tire that is underinflated, the tire
can overheat. An overheated tire
can lose air suddenly or catch
fire. You or others could be
injured. Properly inflate all tires,
including the spare.
See Tire Pressure on page 10 55,
for information on proper tire
inflation.
