AIRLESS TIRE

An airless tire includes a tread ring, a hub formed on radial direction inner side of the ring to be fixed to an axle, and a spoke structure connecting the ring and hub. The ring includes a tread rubber layer, a first reinforcing cord layer, a second reinforcing cord layer and a shear rubber layer between the first and second cord layers, the first and second cord layers and shear layer are formed such that ratio Eb/Ee between tire circumferential direction tensile modulus Ebof the first cord layer and shear modulus Ee of the shear layer is 100 or greater and that ratio Eb/Ee between tire circumferential direction tensile modulus Ebof the second cord layer and shear modulus Ee is 100 or greater, and each cord layer has a topping rubber having loss tangent tanδb of 0.03 to 0.10 and tensile modulus E*b of 4 to 20 MPa.
