GMC 2010 Sierra Owner's Manual page 550

The dual tires are rotated as a pair, and the inside
rear tires become the outside rear tires.
When you install dual wheels, be sure the vent
holes in the inner and outer wheels on each side
are lined up.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. See Inflation - Tire
Pressure on page 6 80 and Loading the Vehicle on
page 5 33.
Make certain that all wheel nuts are properly
tightened. See Wheel Nut Torque under
Capacities and Specifications on page 6 137.

If your vehicle has dual
rear wheels and the
tread design for the
front tires is different
from the dual rear tires,
always use the correct
rotation pattern shown
here when rotating the
tires.
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 you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a
cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if needed, to get all the rust or dirt off.
See Changing a Flat Tire on page 6 100.
If your vehicle has a Tire Pressure Monitor
System (TPMS), reset the TPMS sensors after
rotating the tires. See Tire Pressure Monitor
Operation on page 6 84.
Make sure the spare tire, if your vehicle has one,
is stored securely. 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
on page 6 116.
