Description
耐摩耗性:20000km走行後のトレッドの摩耗量を測定し、測定結果を指数化した。指数が大きいほど摩耗量が少なく耐摩耗性に優れることを示す。
耐偏摩耗性:20000km走行後のトレッドの偏摩耗状態(ヒールアンドトゥ摩耗量、及び、センター陸部の摩耗量とショルダー陸部の摩耗量との差)を測定し、測定結果を指数化した。指数が大きいほど偏摩耗が少なく耐偏摩耗性に優れることを示す。
トラクション性:トレッドの陸部が70%摩耗した状態で、水深1mmの路面上で、停止状態から20m進むまでに要する時間を測定し、測定結果を指数化した。指数が大きいほど要する時間が短くトラクション性に優れることを示す。
