Abstract
【解決手段】トレッド部、タイヤ周方向にのびる陸部が設けられた空気入りタイヤであり、陸部には、陸部のタイヤ軸方向の一方の端縁から他方の端縁に向かって直線状にのびる直線部34と、直線部34から他方の端縁までの間を円弧状に湾曲してのびる円弧部33とを含む複合サイプ35が複数設けられており、複数の複合サイプ35は、円弧部33の最大深さが直線部34の最大深さよりも大きい第1複合サイプ36と、直線部34の最大深さが円弧部33の最大深さよりも大きい第2複合サイプ37とを含んでいる空気入りタイヤ。
【選択図】図2
Description
図1は、本発明の一実施形態を示す空気入りタイヤ1のトレッド部2の展開図である。本実施形態の空気入りタイヤ(以下、単に「タイヤ」ということがある)1は、例えば、冬用の乗用車用タイヤとして好適に用いられる。
装着リム:16×6J
タイヤ内圧:240kPa
テスト車両:排気量2400cc、前輪駆動車
タイヤ装着位置:全輪
氷雪路面で制動したとき及び旋回したときの性能が、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、氷雪路面での制動性能又は旋回性能が優れていることを示す。
ドライ路面を走行したときの操縦安定性が、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、ドライ性能が優れていることを示す。
テスト結果が表1に示される。
