Abstract

　石噛み対策を施す上でタイヤの長寿命化を図った空気入りタイヤを提供することを課題とするものであり、トレッド部１８に形成されたセンター主溝２０の、ジグザグ状に折れ曲がる屈曲部２４の溝底にのみ石噛み防止用突起２８を配置するとともに、隣り合う屈曲部同士を接続する直線部２６の溝壁の、トレッド法線方向に対する溝壁角度を、屈曲部２４の溝壁のトレッド法線方向に対する溝壁角度よりも大きくする。これにより、直線部２６では、石噛み防止用突起を配置していなくても従来と同等のレベルで石噛みし難くすることができる。従って、石噛み防止用突起２８の配置数を従来よりも大幅に低減させることができ、タイヤが使用可能である状態で石噛み防止用突起２８がタイヤ表面に出てくる確率が大幅に低減する。
