A motor vehicle wheel frame 10 is in the form of an assembly including three main components 12, 14, 30 of fiber-reinforced synthetic plastics molded material and a pre-assembled hub 32. First and second members 12, 14 are mirror images. Each includes a circular band portion 16, 18; a plurality of spoke portions 20, 22, extending inwardly from the band portions; and hub mounting arrangements 24, 26 in the form of an inner peripheral flanges at inner ends of the spoke portions. The first and second members are closed on each other to form an outer, circular, outwardly concave band 28, a plurality of hollow spokes and the hub mounting formations in opposed arrangement. The third main component is a rim 30 seated in the concave band 28 and adapted to seat a tire. The hub 32 is received intermediate the hub mounting formations. The three main components and the hub are assembled together and bonded together by suitable resinous adhesives.
