Abstract
Description
ウェット路テストコースにおいて、時速100km/hで直進走行中の乗用車に制動を付与し、停止するまでの距離を測定した。これを各試験タイヤについて5回行い、最大と最小の距離を除いた3回の平均距離を求め、その結果を従来タイヤを100とする指数値で示した。この値が大きい程ウェット制動性に優れている。
雪路テストコースにおいて、テストドライバー3名によるフィーリングテストを実施し、その結果を3名による平均値で評価し、従来タイヤを100とする指数値で示した。この値が大きい程雪上トラクション性に優れている。
氷路テストコースにおいて、時速40km/hで直進走行中の乗用車に制動を付与し、停止するまでの距離を測定した。これを各試験タイヤについて5回行い、最大と最小の距離を除いた3回の平均距離を求め、その結果を従来タイヤを100とする指数値で示した。この値が大きい程氷上制動性に優れている。
