To provide a pneumatic tire that can be suppressed from deterioration in traction performance.SOLUTION: On the assumption that a first-axial directional virtual line 61 extends in a tire axial direction through a ridge line between a first surface 51 and a second surface 52 of a side surface 21 and a second-axial directional virtual line 62 passes through a position corresponding to 75% of a main groove depth D1 in a tire radial direction of the main groove 22, from a tread face 20 toward the inside in the tire radial direction and extends in the tire axial direction, outer ends in the tire radial direction of a plurality of side surface sipes 60 are respectively positioned on the first-axial directional virtual line 61 or closer to the inside in the tire radial direction than the first-axial directional virtual line 61, and inner ends in the tire radial direction of the plurality of side surface sipes 60 are respectively positioned on the second-axial directional virtual line 62 or closer to the outside in the tire radial direction than the second-axial directional virtual line 62.SELECTED DRAWING: Figure 3 【課題】トラクション性能の低下が抑制される空気入りタイヤを提供する。【解決手段】側面２１の第１面５１と第２面５２との間の稜線を通りタイヤ軸方向に延びる第１軸方向仮想線６１、及び踏面２０からタイヤ径方向の内側へ主溝２２のタイヤ径方向の主溝深さＤ１の７５％の位置を通りタイヤ軸方向に延びる第２軸方向仮想線６２を仮定すると、複数の側面サイプ６０のタイヤ径方向の外端は、第１軸方向仮想線６１上、又は第１軸方向仮想線６１よりもタイヤ径方向の内側にそれぞれ位置しており、複数の側面サイプ６０のタイヤ径方向の内端は、第２軸方向仮想線６２上、又は第２軸方向仮想線６２よりもタイヤ径方向の外側にそれぞれ位置している。【選択図】図３
