Abstract
To provide a tire tube having excellent sealing performance and long lasting durability. The tire tube contains a primary and secondary cavity, each having multiple ports. In the event of a tire rupture or puncture within the primary cavity, the secondary cavity can be inflated manually through a secondary tire valve, or via a rapid pressurization utilizing an actuation value and a pressurized cavity within the rim structure. An adhesive impregnated rubber or synthetic layer bonded to a tubular layer will form the boundary between the wall separating the primary and secondary cavities, and provide a filler to seal the leak in the primary cavity tube outer wall, and into the tire itself.
