Claims (3)
- トレッド部にタイヤ周方向に沿って延びる少なくとも4本の主溝が設けられ、タイヤ接地幅をTWとし、タイヤ幅方向最外側の前記主溝におけるタイヤ幅方向外側の側壁からタイヤ赤道線までのタイヤ幅方向長さをL0とするとき、0.3(TW/2)≦L0≦0.6(TW/2)の条件を満たす乗用車用の空気入りタイヤであって、
前記タイヤ赤道線からタイヤ幅方向外側に至るタイヤ幅方向中央領域Lcの端部が、前記タイヤ幅方向長さL0よりもタイヤ幅方向で広い0.33(TW/2)≦Lc≦0.63(TW/2)の範囲に設定され、正規リムに組んで規定内圧の5%充填時にて、前記タイヤ幅方向中央領域Lcのトレッド面が、タイヤ幅方向中央領域Lcの端部に一致するタイヤ径方向最大位置のトレッド面よりもタイヤ径方向内側に凹む凹部を有し、当該凹部は、タイヤ赤道線上でのタイヤ径方向内側への凹み量δpが最も大きく、当該凹み量δpは、前記トレッド面のタイヤ径方向最大位置から2.0[mm]以下の範囲に設定されていることを特徴とする空気入りタイヤ。 - 前記タイヤ幅方向中央領域Lcのトレッド面は、滑らかに湾曲形成されていると共に、前記タイヤ幅方向外側領域Lsのトレッド面に対して段を有さず連続して設けられていることを特徴とする請求項1に記載の空気入りタイヤ。
- 前記主溝により前記トレッド部に区画形成される陸部が、タイヤ周方向に延びるリブ状の陸部であることを特徴とする請求項1または2に記載の空気入りタイヤ。
