WHEEL & TIRE MAINTENANCE Proper Ɵre inflaƟon and correct installaƟon of rims and wheels is essenƟal to safe, economical, trouble-free service. Check Ɵre pressures daily. Recommended inflaƟon pressure is noted on VIN Data Plate. DO NOT over-inflate Ɵres, as this is a common cause of rim failures and accidents. Never run vehicle on one Ɵre of a dual wheel assembly. Loss of air in one Ɵre of a dual set excessively overloads the other Ɵre if the vehicle is operated in this condiƟon. When checking Ɵre pressures, visually check studs and rim for looseness, cracks or other damage. Inspect Ɵres for uneven wear, cuts, cracks, etc., which would render the Ɵre unfit for further service. If the least doubt exists as to the Ɵres’ serviceability, replace the Ɵre.
DANGER Be extremely careful when working with Ɵres and wheels. Tires and wheels can come apart with explosive force.
Recommended InstallaƟon Procedure-Disc Wheels
1. Check all parts for damage, including wheels and rings. Insure that all studs, nuts and mounƟng faces of hub and wheels are clean and free from grease. Replace any defecƟve parts. 2. Mount inner dual wheel over studs, being careful not to damage stud threads. 3. Mount the outer wheel, being careful not to damage stud threads and hand Ɵghten wheel nuts. 4. Tighten nuts fully, using a crossing paƩern as shown in figure 20. Be sure to Ɵghten nuts only to the recommended torque. The correct wheel nut torque is 450-500 Ō-lbs. (dry).
