and Health Administration publications entitled “Demounting and
Mounting Procedures for Truck/Bus Tires” and “Multi-piece Rim
Matching Chart,”
the National Highway Traffic Safety Administration
(NHTSA) publications entitled: “Demounting and Mounting Procedures

– means the opposite of mounting.
Multi-piece rim wheel
– means the assemblage of a multi-piece
wheel with the tire tub and other components.
Multi-piece wheel
– means a vehicle wheel consisting of two or
more parts, one of which is a side or locking ring designed to hold the
tire on the wheel by interlocking components when the tire is inflated.
Restraining device –
means an apparatus such as a cage rack,
assemblage of bars and other components that will constrain all rim
wheel components during an explosive separation of a multi-piece
wheel, or during the sudden release of the contained air of a single
piece rim wheel.
Rim manual
– means a publication containing instructions from the
manufacturer or other qualified organization for correct mounting,
demounting, maintenance, and safety precautions peculiar to the
type of wheel being serviced.
Rim wheel
– means an assemblage of tire, tube and liner (where

Single piece wheel
– means a vehicle consisting of one part,
designed to hold the tire on the wheel when the tire is inflated.
Trajectory
– means any potential path or route that a rim wheel
component may travel during an explosive separation, or the
sudden release of the pressurized air, or an area at which an
airblast from a single piece rim wheel may be released. The
trajectory may deviate from paths which are perpendicular to the
assembled position of the rim wheel at the time of separation or
explosion. (See Appendix A of this manual for examples of
trajectories.)
Wheel
– means that portion of the rim wheel which provides the
method of attachment of the assembly to the axle of a vehicle
and also provides the means to contain the inflated portion of the
