To provide a pneumatic tire which can improve wet performance in addition to drive performance.SOLUTION: A pneumatic tire 10 includes a tread 20 with a block 30 where a siping 40 is formed. A plurality of recesses 41 are formed on one side wall surface of the siping 40, and volume of the recess 41 increases over a whole tire width in a tire axial direction X as going to an outer side in the tire axial direction X. A plurality of the blocks 30 are formed in the tire axial direction X and volume of the recess 41 of the siping 40 in each block 30 is the same.SELECTED DRAWING: Figure 3

    【課題】駆動性能を向上させると共にウェット性能を向上させることができる空気入りタイヤを提供する。【解決手段】サイプ40が形成されたブロック30を含むトレッド20を有する空気入りタイヤ10であって、サイプ40の一方の壁面には、複数の窪み41が形成され、窪み41は、タイヤ軸方向Xのタイヤ幅全体においてタイヤ軸方向Xの外側に向かうに従って体積が大きくなる。また、ブロック30は、タイヤ軸方向Xに沿って複数形成され、それぞれのブロック30のサイプ40の窪み41の体積は同じである。【選択図】図3
