Patent ID: 10155416

Abstract:
An airless tire includes a tread ring, a hub positioned on radial direction inner side of the tread ring, and a spoke structure connecting the tread ring and hub. The tread ring includes a reinforcing body including a first reinforcing cord layer, a second reinforcing cord layer and a shear layer such that the first layer is extending in tire circumferential direction, the second layer is positioned on tire radial direction inner side of the first layer and extending in the tire circumferential direction, and the shear layer including elastomer is positioned between the first and second layers, and the shear layer includes first and second portions such that the first portion has loss tangent tan δ and shear modulus Ee in MPa at temperature of 30° C. satisfying tan δ≤0.06 and Ee/tan δ≥1500 and the second portion is formed of material different from material of the first portion.
