Dual Tire Operation; Tire Inspection And Rotation - Chevrolet 2006 Express Van Owner's Manual

Dual Tire Operation

When the vehicle is new, or whenever a wheel, wheel bolt
or wheel nut is replaced, check the wheel nut torque after
100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km)
of driving. For proper wheel nut tightening information,
see "Removing the Flat Tire and Installing the Spare Tire"
later in this section, under Changing a Flat Tire on
page 5-71. Also see "Wheel Nut Torque" under
Capacities and Specifications on page 5-99.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more evenly
and last longer if you rotate the tires periodically. See Tire
Inspection and Rotation on page 5-61. Also see
Scheduled Maintenance (Gasoline Engine) on page 6-4.
CAUTION:
{
If you operate your vehicle with a tire that is
badly underinflated, the tire can overheat.
An overheated tire can lose air suddenly or
catch fire. You or others could be injured.
Be sure all tires (including the spare) are
properly inflated.
See Tires on page 5-53 and Inflation - Tire Pressure on
page 5-59 for more information on proper tire inflation.

Tire Inspection and Rotation

Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See When It Is Time
for New Tires on page 5-63 and Wheel Replacement
on page 5-67 for more information.
Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If it moves, use
the ratchet/wheel wrench to tighten the cable. See
Changing a Flat Tire on page 5-71.
If your vehicle has dual rear wheels, also see Dual Tire
Operation on page 5-61.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See Scheduled Maintenance
(Gasoline Engine) on page 6-4.
