Safety pneumatic tire for the biclycle

Abstract

The object of this invention is to provide a safety pneumatic tire for the bicyclist. The new safety pneumatic tire comprises an improved outer cover (or tire) and an improved inner tube. The improved inner tube is incorporated inside the improved tire and both are mounted on a tubeless rim (rather than a traditional rim). A) The improved tire consists of an elastomeric material coating that is applied to the beads of the tire to obtain an elastic property. The elastomeric-covered beads and the tubeless rim naturely join closely to form a completely sealed chamber between the tire and the tubeless rim. B) The improved inner tube consists of an elastic rubber part that is added to the outer base of the air valve body or is added to the entire outer body of the air valve to form an air tight seal with the rim valve opening. The joints and the connections between the improved tire, the improved inner tube and the tubeless rim are tightly sealed to form an enclosed chamber so that, if the inner tube is punctured, the compressed air remains inside the enclosed chamber and does not immediately deflate. As a result, any deflation of tire occurs slowly and the bicyclist is protected from falling and is able continue riding. The present invention is also able to avoid the difficulty of air inflation which exists in tubeless tires. In tubeless tires, if inflation of the tire is not rapid enough to create sealing pressure between the tire beads and the tubeless rim bead seat, air will escape during the process of inflation. With the present invention, this difficulty is avoided with the use of the improved inner tube.
