Abstract

A safety tyre and wheel assembly of the type described in UK Patent Specification No. 1,522,028 is modified in that the elastomeric spacer rings 40, 42 are provided with annular reinforcements 44, 46 so as to be circumferentially inextensible but laterally elastic whereby the rings are compressible between the tyre beads 20, 22 and the bearing member 28 but radially outward displacement of the rings in use is prevented. The rotatable tyre support 38 may have a curved, as shown, or conic, surface 34 engaged with a corresponding surface 30 of the bearing member, and the latter may be made of molybdenum disulphide impregnated nylon. The support 38 and bearing member 28 may be formed by interconnected arcuate segments. <IMAGE>
