Abstract

　ショルダーリブ３に、トレッド周方向に連続して延びる細溝４を設ける。トレッド幅方向断面内で、細溝４の溝底に繋がるトレッド赤道面側の溝壁４ａに、周方向に連続する環状溝８を設ける。環状溝のトレッド幅方向断面内の形状が、トレッド赤道面側の溝壁に繋がる角部に曲率半径Ｒ１の丸みを、環状溝の奥部のタイヤ径方向外側部分の角部に曲率半径Ｒ２の丸みを、環状溝の奥部のタイヤ径方向内側部分の角部に曲率半径Ｒ３の丸みを、トレッド端側の溝壁４ｂに繋がる角部に曲率半径Ｒ４の丸みを、それぞれ帯びて形成されている。本発明に拠れば、耐石噛み性、耐ディフェンスグループテア性、並びに耐溝底クラック性をそれぞれ向上させることが可能である。
