Wheels and Tires: Description and Operation
Description and OperationSafety Precautions
WARNING: Never run the engine with one wheel off the ground, for example, when changing a tire. The wheel(s) resting on the ground could cause the vehicle to move.
WARNING: The tire and wheel must always be properly matched. It is very important to determine the size of each component before any assembly operations commence. Failure to adhere to these instructions can result in an explosive separation and cause serious bodily injury or death.
WARNING: Aftermarket aerosol tire sealants are extremely flammable. Always question the customer to make sure these products have not been used.
WARNING: Aftermarket wheel assemblies may not be compatible with the vehicle. Use of incompatible wheel assemblies can result in equipment failure and possible injury. Use only approved wheel assemblies.
WARNING: Use only wheels and lug nuts that have been designed for current model year Ford trucks. Aftermarket wheels or lug nuts may not fit or function properly, and can cause personal injury or damage the vehicle.
WARNING: Always wear safety goggles or a face shield when performing any work with tire and wheel assemblies.
CAUTION: Do not clean aluminum wheels with steel wool, abrasive-type cleaners or strong detergents. Use Custom Bright Metal Cleaner 8A-19522-A or equivalent meeting Ford specifications ESR-M5B194-B.
CAUTION: Reduce the air pressure as much as possible by pushing the valve core plunger in prior to removing the valve core. Avoid working in a position in which the face or body is directly over a tire in which there is pressure.
When performing any inspection or repair procedures on wheels (1007) and tires, follow the preceding safety precautions.
Wheels and Tires
WARNING: Do not mix different types of tires, such as radial, bias, or bias-belted, on the same vehicle except in emergencies. Vehicle handling can be seriously affected and can result in loss of control.
Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including full-rated load capacity when inflated to recommended inflation pressures.
