Description
各試験タイヤをリムサイズ16×7Jのホイールに組み付けて、空気圧を350kPaとして試験車両に装着し、舗装路面において10,000kmを走行し、走行後の摩耗量を測定した。評価結果は、測定値の逆数を用いて、標準例1の値を100とする指数にて示した。この指数値が大きいほど摩耗量が小さく耐摩耗性に優れることを意味する。
各試験タイヤをリムサイズ16×7Jのホイールに組み付けて、空気圧を350kPaとして、室内ドラム試験機(ドラム径:1707mm)を用いて、JATMA イヤーブック2009年版記載の当該空気圧における最大負荷荷重の85%に相当する荷重を負荷してドラムに押し付けた状態で、速度80km/hで走行させたときの転動抵抗を測定した。評価結果は、測定値の逆数を用いて、標準例1の値を100とする指数で示した。この指数値が大きいほど転動抵抗が小さく、低転がり性能に優れることを意味する。
各試験タイヤをリムサイズ16×7Jのホイールに組み付けて、空気圧を350kPaとして試験車両に装着し、ウェット路面においてテストドライバーによる操縦安定性能の官能評価を行った。評価結果は、標準例1を基準(3点)とする5点法にて示した。この評価点が大きいほどウェット性能(ウェット路面での操縦安定性)が優れていることを意味する。
各試験タイヤをリムサイズ16×7Jのホイールに組み付けて、空気圧を350kPaとして試験車両に装着し、未舗装路において1,000kmを走行した後、タイヤを目視で観察して外傷の数を計測した。評価結果は以下の五段階で示した。この評価点が「4」であれば従来レベルの良好な耐久性を維持し、評価点が「5」であると特に優れた耐久性を発揮したことを意味する。
1:外傷数が20以上、2:外傷数が11〜20、3:外傷数が6〜10、4:外傷数が2〜5、5:外傷数0〜1
