- トレッドの接地端とサイドウォールとの間のバットレス部の表面に、タイヤ半径方向外側に向かって変位しながらタイヤ周方向に延びる湾曲凹部が設けられ、前記湾曲凹部は、そのタイヤ周方向の両端部のうち接地端側の端部でサイドウォール側の端部よりもタイヤ周方向に対する角度が小さくなるように湾曲して延びており、
前記トレッドが、前記接地端を越えて前記バットレス部に延在するショルダーブロックをタイヤ周方向に並べて設けたショルダーブロック列を含み、前記湾曲凹部が、横溝を挟んで互いに隣接するショルダーブロック間に跨がるように一方のショルダーブロックから前記横溝を越えて他方のショルダーブロックに延在して設けられている、タイヤ。 - 前記湾曲凹部は、前記接地端側の端部で前記サイドウォール側の端部よりも幅が狭く形成された、請求項1に記載のタイヤ。
- 前記湾曲凹部は、前記バットレス部の表面においてタイヤ周方向に間隔をおいて複数設けられ、互いに隣接する湾曲凹部において一方の湾曲凹部の接地端側の端部と他方の湾曲凹部のサイドウォール側の端部とがタイヤ周方向において重複している、請求項1又は2に記載のタイヤ。
- 前記湾曲凹部は、タイヤ半径方向外側の外縁とタイヤ半径方向内側の内縁とを含み、前記外縁に前記バットレス部の表面から前記湾曲凹部の底部に向かって傾斜する傾斜面が設けられた、請求項1~3のいずれか1項に記載のタイヤ。
- 前記トレッドの子午線断面プロファイルが前記接地端を含むその両側近傍部において湾曲状に形成された、請求項1~4のいずれか1項に記載のタイヤ。
