Many workplaces service large vehicle wheels, such as those found on trucks and buses. These operations require trained service personnel as well as physical safeguards to protect against parts flying off the wheel and other hazards. Servicing tires on rim wheels, both multipiece and single-piece, can result in a wheel being propelled great distances, causing serious injury or death to anyone in the trajectory.

The Occupational Safety and Health Administration (OSHA) provides the 29 CFR 1910.177 —Servicing multipiece and single-piece rim wheels standard that applies only to servicing multipiece and single-piece rim wheels used on large vehicles such as trucks, tractors, trailers, buses, and off-road machines. It does not apply to servicing rim wheels on automobiles, or on pickup trucks and vans utilizing automobile tires or truck tires designated “LT.”
