Abstract

Disclosed is a pressurizable inner multi chambered tube for a tire having resilient radial walls in the body sealingly the chambers from one another. A ring shaped manifold on the tube communicates to the chambers by a check valve at each chamber, the check valves permitting fluid flow from the manifold to the chambers but preventing flow in the reverse direction. A valveless fluid passing fixture on the manifold permits the manifold to be connected to a source of pressurized air. If one chamber of the tube looses pressure, the remaining tubes will expand in an angular, circumferential direction and slide on the manifold so as to take up space formerly occupied by the one, depressurized chamber. The check valves of the remaining chambers will be released from engagement as the remaining chambers slide on the manifold.
