That is, if the cross-sectional shape of the shoulder groove 7 in the tire width direction is changed in the tire circumferential direction, there is a possibility that a portion where the groove volume is reduced occurs and the wet performance is deteriorated. In particular, when the shoulder groove 7 extends in a zigzag shape in the circumferential direction, stress may concentrate on the acute angle portion and cracks may occur. To avoid this, the cross-sectional shape should be uniform in the tire circumferential direction. It is advantageous to do so.

- the deepest portion 16 of the groove bottom is lowered from the center 17 of the opening edges 9 and 12 to the tire rotation axis in the cross section of the shoulder groove 7 in the tire width direction.
- the normal line 18 is located on the tire equator side.
- the maximum depth of the shoulder groove is preferably 17 to 25 mm.

Abstract
Description
(1)タイヤのトレッドの表面に、タイヤの周方向に延びる複数本の周方向溝を有するタイヤであって、
前記周方向溝のうち、タイヤ幅方向最外側に配置された周方向溝は、タイヤ幅方向断面において、タイヤ幅方向外側の溝壁と、該周方向溝のタイヤ幅方向外側の開口縁における接線とが成す角度が、タイヤ赤道側の溝壁と、該周方向溝のタイヤ幅方向外側の開口縁とタイヤ赤道側の開口縁における接線とが成す角度よりも大きく、且つ何れの角度も90°以上100°未満であることを特徴とするタイヤ。
前記周方向溝が8本であり、該周方向溝及びトレッド端にて区画される陸部のうち、タイヤ幅方向最外側に位置する陸部の幅がトレッド半幅の20~40%であり、且つ前記タイヤ幅方向最外側に位置する陸部のタイヤ幅方向内側に隣り合う陸部の幅が、前記タイヤ幅方向最外側に位置する陸部の幅の60~80%であることを特徴とするタイヤ。
該ショルダー溝7は、図2のA-A線に沿う断面図である図3に示すように、タイヤ幅方向外側の溝壁8と、該トレッド3の踏面の輪郭線30の、周方向溝のタイヤ幅方向外側の開口縁9における接線10とが成す角度αが、タイヤ赤道側の溝壁11と、該トレッド3の踏面の輪郭線30の、周方向溝のタイヤ赤道側の開口縁12おける接線13とが成す角度βよりも大きく、更に、これら角度αおよびβが90°以上100°未満であることを特徴とする。
なお、角度αおよびβを規定する溝壁8および11が、平面状でなく曲面である場合は、ショルダー溝7の開口縁から溝深さの1/3の深さにおける当該曲面上の接線を溝壁8または11とし、それぞれ接線10または13との間で角度αまたはβを規定すればよい。
ここで、本発明のタイヤにおいては、角度αを角度βよりも大きくすることによって、摩耗の激しいタイヤ幅方向外側の開口縁9付近の剛性が上がり、一方、該開口縁9付近ほど摩耗の激しくないタイヤ赤道側の開口縁12付近の剛性が開口縁9付近よりも下がるため、結果として、トレッドの幅方向外側付近で生じやすい偏摩耗を緩和できる。また、前記角度αと角度βとが100°以上であると、開口縁付近の剛性が低下して偏摩耗が発生しやすくなる。
なお、図2に記載のタイヤのトレッドパターンは、6本のタイヤ周方向溝と、2本のショルダー溝と、これら周方向溝をつなぐタイヤ幅方向溝とからなるが、該周方向溝の本数及びタイヤ幅方向溝の構成は、特に限定されず適宜選択できる。
なお、前記溝壁の底部14及び15の範囲としては、上記曲率半径を満たす部分が溝底の最深部16の隣接域に存在している限り特に限定されず、適宜選択できる。
なお、本発明のタイヤは、重荷重用空気入りラジアルタイヤとして好適に使用できる。
比較例1のタイヤとして、図1に示す構成で、ベルト5が一層の周方向ベルト及び各々タイヤ周方向に対して39°の角度をなす2層の角度付きベルトからなり、図5に示すトレッドパターンを有するタイヤであって、このショルダー溝7は図4(図5のA-A線断面)に示す形状を有し、ここで溝の深さ、溝幅、溝底の底部14及び15の曲率半径が表1に示す値であり、タイヤサイズが445/50R22.5であるタイヤを製造した。また、比較例2及び実施例1~7のタイヤとしては、図1に示す構成で、ベルト5が一層の周方向ベルト及び各々タイヤ周方向に対して39°の角度をなす2層の角度付きベルトからなり、図2に示すトレッドパターンを有するタイヤであって、このショルダー溝7は図3に示す形状を有し、ここで溝の深さ、溝幅、溝底の底部14及び15の曲率半径が表1に示す値であり、タイヤサイズが445/50R22.5である空気入りタイヤを製造した。これら空気入りタイヤを、リムサイズ:14.00のリムに組み付け、内圧を690kPaとして、3860kgの荷重をかけて、下記の方法により溝開き量評価試験及び偏摩耗試験(室内試験)を、また、実車試験として、下記の方法により車両燃費試験及び偏摩耗試験(実車試験)を行なった。結果を表1に示す。
溝開き量試験の評価は、タイヤに正規荷重をかけた状態での、溝のタイヤ周方向の幅と、ブロックの交点間(図3の9~12の間)の距離を測定することによって行なった。比較例1の値を100として実施例の値を指数化した。指数が小さいほど評価が良好であることを示す。
ショルダー部の摩耗エネルギーの評価は、自由転動時、駆動力負荷時、横力負荷時、及びキャンバー設定時において、タイヤ踏面のブロック部のせん断力を測定することによって行なった。比較例1の値を100として実施例の値を指数化した。指数が小さいほど評価が良好であることを示す。
車両燃費試験の評価は、前記タイヤを装着した車両を走行させて、該車両の燃料消費量を測定することによって行なった。比較例1の値を100として実施例の値を指数化した。指数が小さいほど評価が良好であることを示す。
偏摩耗試験の評価は、接地面内のブロックの動きと接地圧分布を測定することで行なった。比較例1の値を100として実施例の値を指数化した。指数が小さいほど評価が良好であることを示す。
