PURPOSE:To provide a tire with good elasticity and improve riding comfort by forming a three layer structure with a tread rubber, center rubber and base rubber, and further forming an annular hollow body inside the center rubber with the hollow space filled with an internal pressure. CONSTITUTION:A cushioned tire 1 is formed in a three layer structure with a base rubber 4 reinforced by mixing short strand cords, a center rubber 3 made of a soft rubber and arranged on a radially outer side of the base rubber 4, and a tread rubber 2 having good wear resistance and cut resistance and arranged on the outer side of the center rubber 3. The tire is fitted to a wheel rim 5 by means of the base rubber 4. In this case, an annular hollow body 6 is formed extending in the peripheral direction of the center rubber 3. The annular hollow body 6 is provided with an air value 7 to retain a specified inner pressure. The annular hollow body 6 is surrounded with an annular tube 9 to prevent the air from leaking. |
