Wheels and Tires: Service Precautions

Safety Precautions

WARNING: Vehicle may have multiple drive wheels. Do not use engine to power the driveline unless all drive wheels are elevated off the ground. Drive wheels in contact with ground could cause unexpected vehicle movement. Failure to follow this instruction may result in serious personal injury.

WARNING: Do not mix different types of tires (radial, bias or bias-belted tires) on the same vehicle except in emergencies (temporary spare usage). Vehicle handling may be affected and may result in serious personal injury.

WARNING: Before servicing any tire, ask the customer if anyone injected a tire sealant into the tire. Tire sealants may be flammable and can burn or explode if exposed to an ignition source. Failure to follow this instruction may result in serious personal injury.

WARNING: Replacement wheels must be equivalent to the original equipment wheels in:
^ load carrying capacity.
^ diameter, width and offset.
^ pilot hole and bolt circle.

Combined load carrying capacity of replacement wheels for a given axle, must be equal to or greater than that axle's gross axle weight rating (GAWR) identified on the vehicle's Safety Compliance Certification label. All other specifications should be evaluated by measurement of both the original wheel and the replacement wheel. If specifications are not equivalent, the safety and handling of the vehicle may be degraded, which may result in serious injury to the vehicle occupant(s).

WARNING: Only use the correct wheel nut for the application. Incorrect nuts can come loose and result in wheel separation from vehicle and loss of vehicle control. Failure to follow this instruction may result in serious injury to vehicle occupant(s).

WARNING: Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.

CAUTION: Do not clean aluminum wheels with steel wool, abrasive-type cleaners or strong detergents or damage to the wheel may occur. Use Wheel and Tire Cleaner ZC-37-A or -B or equivalent.

When carrying out any inspection or repair procedures on wheels and tires, follow the preceding safety precautions.
