Wheels and Tires: Service Precautions

Safety Precautions

WARNING: Never run the engine with one wheel off the ground, for example, when changing a tire. The wheel resting on the ground could cause the vehicle to move.

WARNING: The tire and wheel must always be correctly 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: Use only wheels and wheel nuts that have been designed for current model year Ford trucks. Aftermarket wheels or wheel nuts may not fit or function correctly, and can cause personal injury or damage the vehicle.
