ABSTRACT:
A device located within the tubeless tire wall of an automobile tire, capable of preserving this tire wall from the deterioration caused by its own rim, and making it possible for the vehicle to continue rolling even when said tire loses all the air contained in its interior. The device is characterized by a partially flexible ring-shaped nucleus within the tire, attached to the tire rim and adjustably positioned over the central zone of the tire rim. Obliquely projecting flexible wings rise from the base of the ring-shaped nucleus. Each wing has a projecting ring-shaped edge at the side. When the tire is in an uninflated state, the height of the central nucleus is greater than the height of the sum of the tire rim and the thickness of the folded uninflated tire sides. Each wing interposes into the space defined by the folded side walls of the uninflated tire, and the ring shaped edge maintains engagement of the bead with the rim.
