Abstract
Provided is a tire with self-inflation device. The tube is inserted inside the side portion where the extension and contraction movements of the tire are mostly occurring in order to further enhance the efficiency of the air supply to the tire cavity during driving. The air compressed towards the driving direction is injected to the tire cavity, and the air from the outside is charged to the tube due to the negative pressure formed in the tube located in the opposite side of driving. The durability is enhanced by reducing the exposed portion of the regulator.
