To provide a pneumatic tire capable of improving on-snow performance while suppressing occurrence of pattern noise.SOLUTION: In an objective pneumatic tire, plural sipes 11, 12, 13 are provided at intervals on each of a center land part 10A, an intermediate land part 10B and a shoulder land part 10C in a tire circumferential direction. The sipe 11 has a widening part 14 in which a wide groove is formed on one end of the sipe, and the sipe 13 extends from the outside of a ground contact end E in a tire width direction toward a side of an outside main groove 9B. Directions of the sipes 11, 13 to the tire circumferential direction are reverse to that of the sipe 12. The inclination angles θ, θand θof the sipes 11, 12, 13 satisfy a relation of θ<θ<θ<90°. An end part 12a of a side of an inside main groove 9A in the sipe 12 is disposed between end parts 11a of the sipe 11, and at least one of the sipes 11 and 12 exists on a tire meridian even at any position on a tire whole circumference.SELECTED DRAWING: Figure 2

    【課題】パターンノイズの発生を抑制しながら、スノー性能を向上させることを可能にした空気入りタイヤを提供する。【解決手段】センター陸部10A、中間陸部10B及びショルダー陸部10Cの各々にタイヤ周方向に間隔をおいて複数本のサイプ11,12,13が設けられ、サイプ11はその一方の端部に溝幅が広く形成された拡幅部14を有し、サイプ13は接地端Eのタイヤ幅方向外側から外側主溝9Bの側に向かって延在し、サイプ11,13のタイヤ周方向に対する向きがサイプ12とは逆向きであり、サイプ11の傾斜角度θCEとサイプ12の傾斜角度θMDとサイプ13の傾斜角度θSHとがθCE<θMD<θSH<90°の関係を満たし、サイプ12における内側主溝9Aの側の端部12aがサイプ11の端部11aの間に配置され、タイヤ全周のいずれの位置においてもタイヤ子午線上にサイプ11及びサイプ12の少なくとも一方が存在する。【選択図】図2
