Chevrolet 2007 Silverado 1500 Pickup, Owner'S Manual

Page: 552 / 670

See the example following. 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 Your Vehicle on
page 403 .
Example:
You will find the maximum load and inflation
pressure molded on the tire’s sidewall, in small
letters, near the rim flange. It will read something
like this: Maximum load 690 kg (1521 lbs)
300 kPa (44 psi) Max. Press.
For this example, you would set the inflation
pressure for high-speed driving at
38 psi (265 kPa).
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 566 .
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 553 . Also see Scheduled Maintenance
(Gasoline Engine) on page 615 .

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 Inflation - Tire Pressure on page 550 , for
information on proper tire inflation.
