- 前記傾斜部(29a,29b,29c,31)は、前記側壁を画定する前記サイプの深さ(P)の少なくとも5%に等しい半径方向高さ(H)を有する、請求項1乃至3の何れか1項に記載のトレッド。
- 前記傾斜部(29a,29b,29c,31)は、半径方向に対してせいぜい45°に等しい角度(α)だけ傾けられている、請求項1乃至4の何れか1項に記載のトレッド。
- 各ブロック(21a,21b,21c)は、2つの前記傾斜部(29a,29b,29c,31)を有し、各傾斜部は、前記ブロックの前記エッジコーナー部(22a,22b,22c,24)の各々とそれぞれ関連している、請求項1乃至5の何れか1項に記載のトレッド。
