Description
比較例及び実施例に係るタイヤを用いて、乾燥路面における操縦安定性能評価を行った。比較評価に用いたタイヤに関するデータを以下に示す。
・ リムサイズ :7.5J×17
・ 内圧条件 :車両指定圧
・ 荷重条件 :2名相当
実施例に係るタイヤは、第2ブロック部に隣接する外側周溝に隆起部が形成されており、比較例に係るタイヤは、外側周溝の全域に亘って同じ溝深さとなるように構成されており、隆起部が形成されていない。実施例に係るタイヤと比較例に係るタイヤは、外側周溝の構成のみ異なり、その他の構成は同様である。
各タイヤを装着した車両を用いて走行し、操縦安定性をフィーリング評価した。操縦安定性能の評価結果を、比較例に係るタイヤの評価結果を基準したときの対比評価で示す。
