Summary: | 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 groove bottom of a main groove 22 and a second-axial directional virtual line 62 passes through a position corresponding to 50% of a main groove depth D1 in a tire radial direction of s main groove 22, from a tread face 20 to the inside in the tire axial direction and extends in the tire axial direction, inner 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 outside in the tire radial direction than the first-axial directional virtual line 61. Outer 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 inside 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】主溝22の溝底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50%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のタイヤ径方向の内端は、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外側にそれぞれ位置しており、複数の側面サイプ60のタイヤ径方向の外端は、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内側にそれぞれ位置している。【選択図】図3 |
