Abstract: Edge lugged tire carrying rims are locked by fastening assemblies on the spoke members of a vehicle wheel. The rim lugs project radially from a base edge portion carrying a removable bead flange and have an axially inwardly projecting curved body portion with a radially inner lateral surface intersecting a radially directed leg portion. FIGS. 1-3 disclose an outer dual rim mounting on a wheel felloe comprising a radially directed surface and an adjacent radially inner lateral surface using a fastening assembly having a clamp element with dual concentric and segmental axially oriented surfaces and parallel radially directed surfaces. FIGS. 4 and 5 disclose an outer dual rim mounting on a wheel felloe comprising wing portions providing a pair of axially oriented surfaces and a radially directed portion between the wing portions using a fastening assembly having a clamp element with lateral wing portions and parallel radially directed surfaces.

Abstract: A conventional set of dual wheels having rims with tires thereon are effectively locked on a wheel hub mounted on the end of an axle on a trailer chassis by replacing two of the studs and hexagonal nuts, normally provided for holding the dual wheels on the wheel hub, with security bolts. When the threaded ends of the security bolts are engaged on the wheel hub, their cylindrical heads are of such a size as to substantially abut the underside of the cylindrical surface of the rim of the outer wheel of the set of dual wheels. Each security bolt has a square opening provided on the end of the cylindrical head thereof to receive the square projection on the end of an adaptor provided for a wrench which is also used for tightening and loosening the hexagonal nuts. Such a structural arrangement makes it difficult, if not impossible, to loosen the security bolts as needed to remove the wheels from the wheel hub while the trailer is parked at a terminal.

Abstract: Two-piece rim for mounting tires, single or dual, on a wheel. The removable bead ring has an axial projection intended for engagement by restraining means mounted on the wheel in the event a tire on said rim is unintentionally deflated. Various forms of restraining means are provided.

Abstract: A support member for a wheel rim of an off-highway vehicle for facilitating the independent securing of the large wheels and associated disc brakes to the vehicle, and a relief groove on the brake disc for dissipation of heat during a braking operation in order to eliminate or preclude fusing of the disc to stationary elements of the braking apparatus thus facilitating the removal of the disc for replacement or the like.
