See "Wheel Nut Torque" under Capacities and Specifications on page5- 120. 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. Thedual tires are rotated as a pair, and the inside rear tires became the outside rear tires. When you install dual wheels, be sure the vent holes in the inner and outer wheels on eachside are lined up. Rust or dirt on awheel, 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 thewheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to dothis; but be sure to use a scraper or wire brush later, if you need to, to get all the rust ordirt off.
