  • Patent number: 9352617
    Abstract: A hollowed-out non-pneumatic tire with reinforcing ribs comprises a tire body. A row or rows of through holes are uniformly and annularly distributed in the tire body. The through holes are uniformly distributed in the tire body in 360 degrees by taking the central axis of the tire body as a center. The through holes transversely penetrate through the two sides of the tire body. The reinforcing ribs are arranged in the through holes. The hollowed-out non-pneumatic tire with the reinforcing ribs provided by the invention has the advantages that the elasticity is high, the friction area between the tire and the ground is reduced and the driving force of the bicycles, the motorcycles and the automobiles is effectively decreased.
