Dual Tire Operation; Tire Pressure Monitor System - Chevrolet 2010 Silverado Owner's Manual

When you end this high speed driving, return the tires to
the cold inflation pressure shown on the Tire and
Loading Information label. See Loading the Vehicle on
page 5 29 and Inflation - Tire Pressure on page 6 73.

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 torque and wheel nut
tightening information, see Removing the Spare Tire
and Tools on page 6 92.
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 6 80. Also
see Scheduled Maintenance on page 7 3.
WARNING:
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 Inflation - Tire Pressure on page 6 73, for
information on proper tire inflation.

Tire Pressure Monitor System

The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in your
vehicle's tires and transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inflate them to the proper
pressure. Driving on a significantly under inflated tire
causes the tire to overheat and can lead to tire failure.
