Description
各試験タイヤの重量を測定した。評価結果は、測定値の逆数を用い、従来例を100とする指数にて示した。この指数値が大きいほど軽量であることを意味する。
各試験タイヤをリムサイズ16×6 1/2JJのホイールに組み付けて半径854mmのドラムを備えた転がり抵抗試験機に装着し、空気圧210kPa、荷重6.47kN、速度80km/hの条件にて30分間の予備走行を行った後、同条件にて転がり抵抗を測定した。評価結果は、測定値の逆数を用い、従来例を100とする指数にて示した。この指数値が大きいほど転がり抵抗が小さいことを意味する。
各試験タイヤをリムサイズ16×6 1/2JJのホイールに組み付けて試験車両に装着し、空気圧210kPaの条件にて、テストドライバーによるテストコースでの官能評価を実施した。評価結果は、従来例を100とする指数にて示した。この指数値が大きいほど操縦安定性は優れていることを意味する。
各試験タイヤをリムサイズ16×6 1/2JJのホイールに組み付けてドラム耐久試験機に装着し、空気圧440kPa、荷重12.9kN、速度81km/hの条件にて走行試験を実施し、カーカス層のセパレーション故障に至るまでの走行距離を計測した。評価結果は、従来例を100とする指数にて示した。この指数値が大きいほど耐セパレーション性能が優れていることを意味する。
