Dual Tire Rotation; When It Is Time For New; Tires - GMC 2012 Sierra Series Owner's Manual

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 80.
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 68 and
Tire Rotation on page 10 68. 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 62,
for 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.

Vehicle Care
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. Some
commercial truck tires may not have
treadwear indicators. See Tire
Inspection on page 10 68 and Tire
Rotation on page 10 68 for
additional information.
