Abstract

A non-pneumatic tire includes a spoke structure that can be easily mounted on a rim of a wheel. Durability is improved by suppressing the buckling of a spoke structure. A non-pneumatic tire includes a spoke structure (5) and a tread ring (11). The spoke structure (5) includes a cylindrical outer member (2) and a cylindrical inner member (3) which are concentrically arranged, and which are connected to each other with a plurality of fins (4, 4′) arranged at intervals in the circumferential direction. The tread ring (11) fits onto the outer periphery of the spoke structure (5). The spoke structure (5) is divided in the tire circumferential direction into at least two circumferential-direction separate structures (511, 521, 531).
