2006 Chevrolet Silverado 1500 Pickup Owner's Manual - Page 486

If your 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 your tires. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Loading Your Vehicle on page 4-48. Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" under Capacities and Specifications on page 5-132. {CAUTION: 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 the vent holes in the inner and outer wheels on each side are lined up. Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a 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.
