NON-PNEUMATIC TIRE

To provide a non-pneumatic tire that can enhance uniformity of rigidity in a tire circumferential direction while reducing pitch noise.SOLUTION: A non-pneumatic tire 1 comprises: an inner annular part 20; an outer annular part 30 arranged on an outer periphery side of the inner annular part 20, concentrically with the inner annular part 20; a plurality of spokes 40 arranged along a tire circumferential direction to connect the inner annular part 20 to the outer annular part 30; and a tread 50 provided on an outer peripheral surface of the outer annular part 30. The tread 50 has a tread pattern in which a plurality of pitch elements with different pitch lengths P1 are arranged along the tire circumferential direction in a first arrangement pattern, and the plurality of spokes 40 are arranged along the tire circumferential direction at pitches corresponding to pitches of the first arrangement pattern.SELECTED DRAWING: Figure 5 【課題】ピッチノイズを低減しつつ、タイヤ周方向における剛性の均一性を高めることが可能な非空気圧タイヤを提供する。【解決手段】内側環状部２０と、内側環状部２０の外周側に当該内側環状部２０と同軸に配置される外側環状部３０と、内側環状部２０と外側環状部３０とを連結し、タイヤ周方向に沿って配列される複数のスポーク４０と、外側環状部３０の外周面に設けられるトレッド５０と、を備える非空気圧タイヤ１であって、トレッド５０は、タイヤ周方向に沿ってピッチ長Ｐ１の異なる複数のピッチ要素が第１の配列パターンで配列されたトレッドパターンを有し、複数のスポーク４０は、第１の配列パターンと対応したピッチでタイヤ周方向に沿って配列されている。【選択図】図５
