To provide a pneumatic tire including a block having corrugated siping that improves braking performance by suppressing falling down at the time of braking.SOLUTION: A tire an example of an embodiment includes a tread having a block 30 with siping 50 formed therein. The siping has a first wall surface 52 and second wall surface 53 that face each other. Each wall surface 52, 53 includes a corrugated surface with a corrugated profile extending in the tire axial direction when viewed from the outer side of the tire radial direction. On the corrugated surface of the first wall surface 52, at least one first projection 60 is provided at a siping depth direction intermediate position. The first projection 60 faces a second recess provided in the corrugated surface of the second wall surface 53 such that it can engage into the second recess.SELECTED DRAWING: Figure 3

    【課題】波形サイプを有するブロックを含む空気入りタイヤにおいて、制動時の倒れ込みを抑制することにより、制動性能を向上する。【解決手段】実施形態の一例であるタイヤは、サイプ50が形成されたブロック30を有するトレッドを含む。サイプは、互いに対面する第1壁面52及び第2壁面53を有する。各壁面52,53は、タイヤ径方向外側から見た場合にタイヤ軸方向に延びる波形形状を有する波形面を含む。第1壁面52の波形面には、サイプ深さ方向中間位置に少なくとも1つの第1突起60が設けられる。第1突起60が、第2壁面53の波形面に設けられた第2凹みに噛み込み可能に対向している。【選択図】図3
