Description
各試験タイヤをリムサイズ18×7Jのホイールに組み付けて、排気量2500ccの乗用車(前輪駆動車)の前後車輪として装着し、空気圧を230kPaとし、運転席の窓の内側に集音マイクを設置し、アスファルト路面からなるテストコースを平均速度50km/hの条件で走行させた際の周波数315Hz付近の音圧レベルを測定した。評価結果としては、従来例を基準とし、その基準に対する変化量(dB)を示した。
各試験タイヤをリムサイズ18×7Jのホイールに組み付けて、排気量2500ccの乗用車(前輪駆動車)の前後車輪として装着し、空気圧を230kPaとし、アスファルト路面からなるテストコースを平均速度50km/hの条件で走行させた際のロードノイズについて、5人のテストドライバーによる官能評価を行った。評価結果は、従来例1の結果を3点(基準)とする5点法で採点し、最高点と最低点を除いた3名のテストドライバーの点数の平均値を示した。この点数が大きいほどロードノイズ性能(官能測定)が優れることを意味する。
