[0002] [Solution] A tread ring 2 of an airless tire 1 includes a shear rubber layer 7 that is provided between first and second reinforcing cord layers 5, 6 that are respectively arranged on radial direction inner and outer sides. At least one of an inner topping rubber portion (9i) of the first reinforcing cord layer 5 and an inner topping rubber portion (11i) of the second reinforcing cord layer 6 is formed of a rubber composition (G) that contains 10 - 80 parts by weight of an α, β-unsaturated carboxylic acid metal salt with respect to 100 parts by mass of a rubber component, in which a content rate of a butadiene rubber is 10 - 100% by mass, and contains a peroxide.",
