Abstract: A tire assembly inserted in a conventional pneumatic tire that allows the driven vehicle to be operated in a normal operating condition as well as in both a low tire pressure and a “run flat” condition. The tire embodies a multifunctional tire support device that permits the tire even when punctured to continue to support the vehicle and never allows the tire to go entirely flat. The support device when installed reinforces the tire tread and its side walls by applying internal pressure against them should they collapse when tire is punctured. The invention embodies a means for supporting the tire with the multifunctional device and provides an additional embodiment that uses the same device with a backup redundant inner tube to provide support to the punctured or ruptured tire and permits it to be operated in a run flat condition. The inner tube is located in the assembly at a distance away from the tread so that any puncture of the tread would not also puncture the inner tube.

Abstract: The universal system and device of the present invention, once inserted in a conventional pneumatic tire, allows the driven vehicle to be operated in a normal operating condition, as well as in both a low tire pressure and in a run flat condition. For such purpose the tire embodies this device, spherically shaped and not limited in size or quantity. The device is manufactured from rubber, neoprene or equivalent, and in various shore hardness as needed, to permit installation in all tire shapes and sizes, and can be accommodated on all standard or special vehicle rim sizes or configurations. The device is adaptable to automobile, trucks, motorcycles, bicycles or any vehicle that utilizes pneumatic tires and their various uses, including freeway driving, off road, snow and ice, and will adapt to any new configurations of tires and rims such as the low profile tires.
