Description
前記一対のビード部の少なくとも一方に、前記ビード部からタイヤ回転軸方向外側に突出したリムプロテクターを備え、
前記リムプロテクターのタイヤ半径方向外側の側面に、前記リムプロテクターと一体成型された複数の突起を備え、
前記突起の形状は、錐状、半球状、及び、前記リムプロテクターのタイヤ半径方向外側の側面から独立した、頭頂部と柱状側面とを備え、前記頭頂部の全周に前記柱状側面が接続された柱状のいずれかである、ことを特徴とする。
4000cc四輪駆動車にタイヤを装着し、進入速度5km/h及び進入角度5度でタイヤを縁石に接触させた後、縁石に平行に5mだけ走行させたときのリムの損傷程度を目視し確認した。
(ビード部耐久性)
JIS D4230に基づくドラム試験を行い、目視でビード部の故障が確認できるまでの走行距離を測定した。
いずれの結果も比較例を100とした指数として表1に示し、数字が少ないほど性能が良いことを示す。
2 サイドウォール
3 リムプロテクター
4 突起
Claims (4)
- クラウン形状を有するトレッドと、一対のビード部と、前記トレッドと前記ビード部とを連結する一対のサイドウォールを備えた空気入りタイヤであって、
