ABSTRACT:
The drawings illustrate a pneumatic tubeless tire including internal support means. The internal support means comprises a three component system including an inner circumferentially oriented preloaded portion abutted against the wheel rim and normally supporting an outer portion consisting of an endless resilient ring, and an intermediate circumferentially split resilient ring. The latter ring is formed to include side surfaces which match the inner surfaces of the beaded ends for seating thereon when the tire becomes deflated, at which time the inner preloaded portion compresses.
