Dual Tire Rotation; When It Is Time For New; Tires - GMC 2015 Savana Owner's Manual

10-56 Vehicle Care
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10-51.
Check that all wheel nuts are
properly tightened. See Wheel
Nut Torque under Capacities
and Specifications on
page 12-2.
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.

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 wheel nut tightening
information, see Removing the Flat
Tire and Installing the Spare Tire
under Tire Changing on page 10-65.
Also see Wheel Nut Torque under
Capacities and Specifications on
page 12-2.
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 10-55
and Tire Rotation on page 10-55.
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 Tires on page 10-40 and Tire
Pressure on page 10-49 for more
information on proper tire inflation.

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.
