During Tire Changes

WARNING: Alloys or metal surfaces with CRACKS are very dangerous. These components could FAIL without warning during inflation or later on the vehicle. DESTROY all parts that are cracked.

1. Check all metal surfaces. Watch particularly for the following items:
- Cracks in the bead seat area. These are caused by deep rim tool marks, overloading and overinflating tires or using larger than recommended tire sizes.
- Cracks in the front disc brake rotor, between the stud holes or hand holes. These are caused by loose lug nuts, improper installation procedures or the use of incorrect sizes or types of attaching parts.

CAUTION: Make sure that replacements are made with the proper sizes and types of wheels.

2. Replace the parts as necessary.
3. Thoroughly remove rust, dirt and other foreign materials from all surfaces. Hand or electric wire brushes, sand blasting or chemical baths may be used. Bead seat areas of the wheel should be free of rust and rubber deposits.
4. Paint the wheel by brush or spray with a fast-drying metal primer. Surfaces should be clean and dry prior to painting. Make sure that bare metal areas on the outside or tire side of the wheel are covered.
5. Lubricate the tire side of the wheel base just prior to mounting the tire. Avoid the use of any lubricant which contains water or solvent that is injurious to rubber such as WD40. A combination lubricant and rust-preventive compound is preferable such as a rubber lubricant meeting Ford specification ESR-M99B135-A.
6. Inflate tire to the recommended air pressure.
