Abstract
Description
図1は、本発明の一実施形態を示すタイヤ1のトレッド部2の展開図である。本実施形態のタイヤ1は、例えば、乗用車の冬用空気入りタイヤとして好適に使用される。但し、本発明は、このような態様に限定されるものではなく、例えば、重荷重用の空気入りタイヤや、タイヤの内部に加圧された空気が充填されない非空気式タイヤ等の様々なタイヤに用いることができる。
装着リム:17×8.0JJ
タイヤ内圧:270kPa
テスト車両:4輪駆動車、排気量4600cc
タイヤ装着位置:全輪
上記テスト車両でドライ路面を走行したときハンドル応答性、剛性感、グリップ感等を含む操縦安定性が、運転者の官能により評価された。結果は、比較例を100とする評点であり、数値が大きい程、操縦安定性が優れていることを示す。
上記テスト車両で、氷雪上を走行したときのハンドル応答性、発進、制動感、グリップ等及びこれらの持続性が、運転者の官能により評価された。結果は、比較例を100とする評点であり、数値が大きい程、優れた氷雪上性能を有していることを示す。
テストの結果が表1に示される。
