PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of achieving both on-ice performance and dry performance.SOLUTION: A pneumatic tire comprises: a plurality of circumferential grooves 20 extending in a tire circumferential direction; a land part 10 with at least one end in the tire width direction partitioned by the circumferential grooves 20; a bent lug groove 31 having a bent part 34 formed in the land part 10, having one end being open in the circumferential grooves 20 and the other end terminated in the land part 10, and bending at an acute angle in the land part 10; a bottom-up part 41 provided at least in the bent part 34 of the bent lug groove 31 and formed by the bottom of a groove bottom 40 of the bending lug groove 31 being raised; and a through sipe 65 formed in the land part 10 while opening in the circumferential grooves 20 partitioning the land part 10 and formed so as to pass through the groove bottom 40 of the bent part 34 and penetrate between a superior angle side edges 45 of the bent part 34 in the bent lug groove 31.SELECTED DRAWING: Figure 3
【課題】雪上性能とドライ性能とを両立することのできる空気入りタイヤを提供すること。【解決手段】タイヤ周方向に延びる複数の周方向溝20と、タイヤ幅方向における少なくとも一方の端部が周方向溝20によって区画される陸部10と、陸部10に形成されると共に一端が周方向溝20に開口し、他端が陸部10内で終端し、陸部10内で鋭角に屈曲する屈曲部34を有する屈曲ラグ溝31と、少なくとも屈曲ラグ溝31の屈曲部34に設けられ、屈曲ラグ溝31の溝底40が底上げされることにより形成される底上げ部41と、陸部10を区画する周方向溝20に開口して陸部10に形成されると共に、屈曲部34の溝底40を通って、屈曲ラグ溝31における屈曲部34の優角側のエッジ45間を貫通して形成される貫通サイプ65と、を備える。【選択図】図3
