During Tire Changes
WARNING:^ AFTERMARKET AEROSOL TIRE SEALANTS ARE EXTREMELY FLAMMABLE. ALWAYS QUESTION CUSTOMER TO MAKE SURE THESE PRODUCTS HAVE NOT BEEN USED.
^ ALLOYS OR METAL SURFACES WITH CRACKS ARE VERY DANGEROUS. THESE COMPONENTS COULD FAIL WITHOUT WARNING DURING INFLATION OR LATER ON THE VEHICLE CAUSING LOSS OF CONTROL OR PERSONAL INJURY. DESTROY ALL PARTS THAT ARE CRACKED.
CAUTION: Make sure replacements are made with the proper sizes and types of wheels to prevent damage or personal injury.
NOTE: If the tire is to be reinstalled on the same wheel, mark the tire and wheel so they can be reassembled in the same position.
1. Check all metal surfaces. Watch particularly for the following items:
^ Cracks in the rim bead seat or dropwell radii areas. These are caused by deep rim tool marks, overloading and overinflating tires or using larger than recommended tire sizes.
^ Cracks in the wheel disc, 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.
2. Replace the parts as necessary.
3. Thoroughly remove rust, dirt and other foreign materials from all surfaces. Hand or electric wire brushes may be used. Bead seat areas of rim should be free of rubber deposits.
NOTE: 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 ready-to-use liquid soap that meets Ford specification ESR-M99B135-A or equivalent. This protective measure is of particular importance with drop-center tubeless rims as the air in the tire is contained by the tire-side rim surface.
4. Paint rim by brush or spray with a fast-drying metal primer. Surfaces should be clean and dry prior to painting. Make sure bare metal areas on the outside or tire side of rim are covered. This is especially important on drop-center tubeless rims, because warm and sometimes moist air is in constant contact with the metal surface on the tire side of the rim.
5. Lubricate the tire side of the rim base just prior to mounting tire.
CAUTION: When mounting a tire on a wheel, do not inflate to more than 276 kPa (40 psi), then deflate tire to prevent damage or personal injury.
6. Inflate tire to recommended air pressure.
