ABSTRACT:
A spare tire is provided for passenger autos to replace the usual fifth pneumatic tire and wheel assembly supplied as original equipment with autos. The tire includes a metal hub having an annular bulge to provide clearance for the brake calipers of an auto equipped with the tire. A series of rim segment assemblies with tread rubber thereon is mounted on the periphery of the hub member forming the tire rim. Each segment has a T-shaped metal member the T-stem of which is generally trapezoidal in shape and is vulcanized-bonded to a rubber block similar in shape which has an opposite surface vulcanized-bonded to a thin sheet metal segment. Each rim segment assembly is separately connected by suitable means to the hub member. A protective device guarding against tire collapse in event of failure of a bond between the rubber block and a metal member, engages the T-stem and hub member.
