(2) The publications entitled “Multi-piece Rim/Wheel Matching Chart” and “Safety Precautions for Mounting and Demounting Tube/Type Truck Tires,” as revised January 1978, which are hereby incorporated in these rules by reference, shall be accessible and available in the service area. These publications are available from the United States Department of Labor, Occupational Safety and Health Administration, 315 West Allegan, room 315, Lansing, Michigan, 48917, or via the internet at website www.osha.gov, at no charge as of the time of adoption of these rules.

(3) Mating surfaces of the rim gutter ring shall be free of any dirt, surface rust, scale, or rubber buildup before mounting and inflation. (4) A tire shall be completely deflated by removal of the valve core before a wheel is removed from the axle in either of the following situations: (a) When the tire has been driven underinflated at 80% or less of its recommended pressure. (b) When there is obvious or suspected damage to the tire or wheel components. (5) Tires shall be inflated only when constrained by a restraining device, except when the wheel assembly is on a vehicle. Tires may be inflated without being constrained by a restraining device if remote control inflation equipment is used and no employees remain in the trajectory path during inflation in either of the following situations: (a) Tires are underinflated, but have more than 80% of the recommended pressure. (b) Tires are known not to have been run underinflated. (6) When a tire is being partially inflated without a restraining device for the purpose of seating the lock ring or to round out the tube, such inflation shall not exceed 3 psig (0.21 Kg/cm). (7) After tire inflation, the tire rim and rings shall be inspected while still constrained in the restraining device to assure they are properly seated and locked.
