April 26, 2017
[Problem to be solved] To provide an airless tire that is excellent in durability. [Solution] An airless tire 1 includes a cylindrical tread ring 2 that is formed of an elastic body and has a ground contact surface (2a), a hub part 3 that is formed of a substantially non-extensible material and that is arranged on a tire radial direction inner side of the tread ring 2 and is fixed to an axle, and multiple spokes 4 that are formed of an elastic material and are for connecting the tread ring 2 and the hub part 3. The spokes 4 each have the outer edge 6 that is fixed to the tread ring 2 side and the inner edge 7 that is fixed to the hub part 3 side. The outer edge 6 and the inner edge 7 both extend obliquely with respect to a tire axial direction. A compression rigidity (Sr) of the outer edge 6 side of each of the spokes 4 is larger than a compression rigidity (Sh) of the inner edge 7 side of each of the spokes 4.
