Description
圧縮試験機を用いてタイヤに基準負荷(710kgf)の110%及び90%の荷重をかけてそれぞれの縦撓み量を測定し、それらの平均値で基準負荷値を除して縦剛性を測定した。また、タイヤに基準負荷値をかけた状態で、基準負荷の30%の横方向の力を更にタイヤにかけて横撓み量を測定し、その横撓み量の値で横方向の力を除して横剛性を測定した。いずれも比較例1の結果を100として指数で評価し、当該指数が大きいほど剛性が高いことを示す。
テストタイヤを車両に装着して旋回走行、制動及び直進走行を実施した後、ドライバーの官能試験により総合評価した。比較例1の結果を100として指数で評価し、当該指数が大きいほど操縦安定性に優れていることを示す。
