Dual Tire Operation; Tire Inspection And Rotation - Chevrolet 2003 Silverado 1500 Pickup 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 (1 60, 1 600 and
10 000 km) of driving. For proper torque and wheel nut
tightening information, see "Tightening the Wheel
Nuts" later in this section.
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" earlier in this
section. Also see "Scheduled Maintenance Services" in
th 'ndex for scheduled rotation intervals

badly underintlated, 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.
Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 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 5-77 and Wheel Replacement
on page 5-80 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 wheel wrench/hoist shaft to tighten the cable.
See Changing a Flat Tire on page 5-84.
If your vehicle has dual rear wheels, also see Dual Tire
Operation on page 5-74.
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 "Part A: Scheduled
Maintenance Services," in Section 6, for scheduled
rotation intervals.
See "Tires" and "Inflation
-
Tire Pressure" in the Index
for more information on proper tire inflation.
