Abstract

An airless tire includes a tread ring having a cylindrical form and a ground contact surface, a hub positioned on radial direction inner side of the tread ring and formed to be fixed to an axle, and a spoke structure connecting the tread ring and hub. The tread ring includes a tread rubber layer forming the ground contact surface, and a reinforcing rubber layer formed on tire radial direction inner side of the tread layer, and the reinforcing layer is formed of a rubber material obtained by co-crosslinking a rubber composition including a rubber component, an α, β-unsaturated carboxylic acid metal salt and a peroxide such that the metal salt has amount in range of 10 to 80 parts by weight with respect to 100 parts by mass of the rubber component and the rubber component has content rate of butadiene rubber in range of 10 to 100% by mass.
