To provide a pneumatic tire which can improve wet performance in addition to dry performance.SOLUTION: A pneumatic tire 10 comprises a tread 20 including a block 30 where sipings 40 are formed. A plurality of cavities 41 are formed on one wall surface of the siping 40 in which capacity of the cavity 41 becomes smaller at least at one portion in a tire axial direction X as going to outer side in the tire axial direction X, or capacity of the cavity 41 becomes smaller at the whole tire width in a tire axial direction X as going to outer side in the tire axial direction X.SELECTED DRAWING: Figure 3

    【課題】ドライ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の少なくとも一部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小さくなる。また、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小さくなる。【選択図】図3
