ABSTRACT:
The drawings disclose a pneumatic tubeless tire including circumferentially oriented runner segments or a running band. Each segment or band includes support means abutted against the drop center of the wheel rim and an outer portion capable of supporting the weight of the vehicle once the tire becomes deflated. More specifically, in one embodiment, the outer portion extends laterally across the tire, abutting against the oppositely disposed inner surfaces of the tire sidewalls, and in each embodiment, bolts, pins, or hinges are included to serve as the support means for radially supporting and retaining the segments or band in place when the tire becomes deflated.
