A pneumatic tire inflation device and method is disclosed, the device comprising an arrangement of parts that enables its user to selectively gradually inflate a tire at a specified intermediate rate and pressure, and then to selectively suddenly continue such inflation at a substantially greater rate and pressure until complete inflation is achieved.

Pneumatic tire inflation and method

An inner tube assembly for a pneumatic tire, comprising a primary annular tube, a secondary annular tube surrounding the primary annular tube, an annular primary tube-restraining band interpositioned between the primary and secondary tubes, and valves intercommuncating the primary and secondary tubes with one another, is disclosed. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to limit the scope of the invention in any way.

Inner tube assembly for run-flat tires

An inner tube assembly for a pneumatic tire is disclosed. The assembly includes a pair of inner tube systems, one of which surrounds the other and intercommunicates therewith via a valve unit that is adapted to allow a pneumatic fluid to flow unidirectionally from the inner one of such tube systems to the outer one of said tube systems and effect an equilibrium of pressure. The valve unit, however, is adapted to close when the outer one of such tube systems is punctured and undergoes a pressure drop relative to the inner one of such tube systems, thereby to pneumatically isolate the interiors of such tube systems from one another.
