Claims (5)
- 幅方向両端部が一対のビードコア回りに折り返されるとともに、内部にタイヤ赤道Sに対して傾斜した有機繊維からなる複数本のカーカスコードが埋設された2枚以上のカーカスプライから構成され、トロイド状に延びるカーカス層と、カーカス層の半径方向外側に配置されたベルト層と、該ベルト層の半径方向外側に配置されたトレッドと、隣接するカーカスプライ間でベルト層と半径方向に重なり合う位置に配置された補強層とを備え、該補強層を、内部にタイヤ赤道Sに対して傾斜した複数本のスチールからなる補強コードが埋設された少なくとも1枚の補強プライから構成した空気入りタイヤにおいて、前記補強コードのタイヤ赤道Sに対する傾斜角Aを40〜90度の範囲内とするとともに、補強コードに平行な方向における補強層の50mm幅当たりの圧縮剛性Fを1000〜2400Nの範囲内としたことを特徴とする空気入りタイヤ。
- 前記トレッドの踏面を溝により複数の陸部に区画する一方、前記補強層と半径方向に重なる位置に位置している内側陸部のタイヤ幅方向長さを、前記補強層よりタイヤ幅方向両外側に位置している外側陸部のタイヤ幅方向最大長さより小とした請求項1記載の空気入りタイヤ。
- 前記補強コードを複数本のフィラメントを撚ることで構成する一方、該フィラメントの撚りピッチQを、フィラメント径に補強コードを構成するフィラメント本数を乗じた値Vの 1.3〜10.0倍の範囲内とした請求項1または2記載の空気入りタイヤ。
- 前記補強コードとして、曲げ剛性Dが 230〜 300N・m2 の範囲内のコードを用い、また、補強コードを補強層に50mm幅当たり40〜80本打ち込むようにした請求項1〜3のいずれか一項に記載の空気入りタイヤ。
- 前記補強コードのタイヤ赤道Sに対する傾斜角Aを55度以上とした請求項1〜4のいずれか一項に記載の空気入りタイヤ。
