Description
図1には、本実施形態の重荷重用空気入りタイヤ(以下、単に「タイヤ」ということがある。)1の正規状態における回転軸を含むタイヤ子午線断面図が示されている。
装着リム:22.5×9.00
タイヤ内圧:850kPa
ドラム試験機上で上記テストタイヤを規格荷重の200%の条件下で時速20km/hで走行させ、ビード部に損傷が発生するまでの走行距離が測定された。結果は、比較例を100とする指数であり、数値が大きい程、ビード部の耐久性が優れていることを示す。
リムを140℃に加熱し、規格荷重の条件下で時速20km/hで走行させ、ビード部に損傷が発生するまでの走行距離が測定された。結果は、比較例を100とする指数であり、数値が大きい程、ビード部の耐久性が優れていることを示す。
テスト結果が表1及び表2に示される。
