An airless tire comprising: a cylindrical tread ring that is formed of an elastic body and has a ground contact surface; a hub part that is formed of a substantially non-extensible material and that is arranged on a tire radial direction inner side of the tread ring and is to be fixed to an axle; and multiple spokes that are formed of an elastic material and connect the tread ring and the hub part, wherein the spokes each has an outer edge that is fixed on the tread ring side and an inner edge that is fixed on the hub part side, the outer edge and the inner edge both extend obliquely with respect to a tire axial direction, and a compression rigidity (Sr) of the outer edge side of each of the spokes is larger than a compression rigidity (Sh) of the inner edge side of each of the spokes, wherein the compression rigidity (Sr) of the outer edge side of each of the spokes, when the airless tire is in a no-load state, is defined as compression rigidity of an outer edge side portion of each of the spokes between the outer edge and a position a distance away from the outer edge on a tire radial direction inner side and the compression rigidity (Sh) of the inner edge side of a spoke is defined as compression rigidity of an inner edge side portion of the spoke between the inner edge and a position a distance away from the inner edge on a radial direction outer side, wherein the distance and the distance are each 20% of a radial direction length of the spoke, characterized in that for each of the spokes, an actual length (Ls) from the outer edge to the inner edge is 1.01 - 1.10 times a shortest distance (Ld) from the outer edge to the inner edge and wherein a thickness (tr) of the outer edge side of each of the spokes is larger than a thickness (th) of the inner edge side of each of the spokes. a cylindrical tread ring that is formed of an elastic body and has a ground contact surface; a hub part that is formed of a substantially non-extensible material and that is arranged on a tire radial direction inner side of the tread ring and is to be fixed to an axle; and multiple spokes that are formed of an elastic material and connect the tread ring and the hub part, wherein the spokes each has an outer edge that is fixed on the tread ring side and an inner edge that is fixed on the hub part side, the outer edge and the inner edge both extend obliquely with respect to a tire axial direction, and a compression rigidity (Sr) of the outer edge side of each of the spokes is larger than a compression rigidity (Sh) of the inner edge side of each of the spokes, wherein the compression rigidity (Sr) of the outer edge side of each of the spokes, when the airless tire is in a no-load state, is defined as compression rigidity of an outer edge side portion of each of the spokes between the outer edge and a position a distance away from the outer edge on a tire radial direction inner side and the compression rigidity (Sh) of the inner edge side of a spoke is defined as compression rigidity of an inner edge side portion of the spoke between the inner edge and a position a distance away from the inner edge on a radial direction outer side, wherein the distance and the distance are each 20% of a radial direction length of the spoke, characterized in that for each of the spokes, an actual length (Ls) from the outer edge to the inner edge is 1.01 - 1.10 times a shortest distance (Ld) from the outer edge to the inner edge and wherein a thickness (tr) of the outer edge side of each of the spokes is larger than a thickness (th) of the inner edge side of each of the spokes.
