The purpose of the present invention is to minimize decline in endurance, while improving vibration performance. The spokes of an airless tire are provided, as an integrated unit, with an outside annular portion joined to the inside peripheral surface of a tread ring, an inside annular portion joined to the outside peripheral surface of a hub, and a spoke plate portion of constant thickness providing linkage therebetween. The radial inner edge and the radial outer edge of the center plane of thickness of the spoke plate portion are respectively diagonal with respect to a tire axial-direction line. The intersection line at which the center plane of thickness intersects a plane that is at a right angle to the tire axial-direction line constitutes a straight line. The spoke length, which is the length from the radial inner edge to the radial outer edge along the intersection line, is constant for any given location in the tire axial direction. |
