Abstract
An airless tire includes a tread ring including an elastic body and having a cylindrical form and a ground contact surface, a hub including a substantially non-extensible material and positioned on a tire radial direction inner side of the tread ring such that the hub is fixed to an axle, and multiple spokes including an elastic material and connecting the tread ring and the hub. Each of the spokes has an outer edge fixed to the tread ring and an inner edge fixed to the hub such that the outer edge and the inner edge are extending obliquely with respect to a tire axial direction, and the spokes are formed such that the outer edge of each of the spokes has compression rigidity Sr which is greater than compression rigidity Sh of the inner edge of each of the spokes.
