Chevrolet 2010 Express Owner's Manual page 347

If the 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. 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 that vent
holes in the inner and outer wheels on each
side are lined up.
Also see Dual Tire Operation on page 6-70 for
additional information.
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 6-68 and Loading the Vehicle
on page 5-19. Make certain that all wheel nuts are
properly tightened. See "Wheel Nut Torque" under
Capacities and Specifications on page 6-116.
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 6-86.
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 6-72.
Make sure the spare tire 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 6-100.
