- 方向性タイヤトレッド、即ち、回転方向(R)を指示する手段によって示された所定の回転方向を有するトレッドであって、前記トレッドが走行中、路面に接触するよう設計された転動面(30)を有し、前記トレッドが互いに向かい合った壁(11,12)によって境界付けられた複数の切り込み(1)を備え、前記壁の各々は、まず最初に接触パッチに入るエッジに対応した材料要素の前縁(Aa)と呼ばれるエッジ及び前記前縁の次に前記接触パッチに入るエッジに対応した前記材料要素の後縁(Af)と呼ばれるエッジを形成するよう前記転動面(30)から出ており、前記転動面(30)に垂直に測定した高さHの各切り込み(1)が互いに向かい合った壁によって境界付けられていて、前記切り込みと前記転動面の交線を通る前記転動面に垂直な方向と絶対値が55°未満の負の平均角度αをなす少なくとも1つのセグメント(11,101)を有する、トレッドにおいて、 負の角度αの前記セグメント(11,101)は、互いに対向した第1の面(21)と第2の面(22)によって境界付けられた端部(2)を介して前記転動面(30)から出ており、
・前記端部(2)の前記第1の面(21)は、前記転動面に垂直な方向と0°、又は正であり且つ55°未満の平均角度Aをなし、
・前記端部(2)の前記第2の面(22)は、前記転動面に垂直な方向と正であり且つ10°を超える平均角度Fをなしており、
差(F−A)は、10°を超え且つ45°未満である、トレッド。 - 前記角度Aは、20°以下である、請求項1に記載のトレッド。
- 前記切り込みの前記端部(2)は、前記転動面に直角に測定した高さHeを有し、高さHeは、前記切り込みの深さHの5%〜20%である、請求項1または2に記載のトレッド。
- 各切り込み(1)は、負の平均角度αをなして傾斜した部分(101)と正の平均角度βをなして傾斜した部分(102)の一続きを有する、請求項1〜3のうちいずれか一に記載のトレッド。
- 前記角度Fは、値が前記角度βに等しい、請求項4記載のトレッド。
- 各切り込みは、負の平均角度αをなして傾斜した複数の切り込み部分(101)を有し、前記切り込み部分の各々は、平均角度β1,β2の互いに平行ではない面によって境界付けられた中間部分(103)により次の切り込み部分に連結されている、請求項1〜3のうちいずれか一に記載のトレッド。
- 前記角度β1は、前記切り込みの前記端部の前記角度Aに等しく、前記角度β2は、前記切り込みの前記端部の前記角度Fに等しい、請求項6記載のトレッド。
