Abstract
【解決手段】 一対のビード部3,3間にカーカス層4を装架し、カーカス層4の外周側にベルト層6を配置した空気入りタイヤにおいて、熱可塑性樹脂又は熱可塑性樹脂とエラストマーとをブレンドした熱可塑性エラストマー組成物からなるフィルムを含むインナーライナー層7をカーカス層4の内面に沿って配置し、インナーライナー層7を各ビード部3に埋設されたビードコア5の廻りにタイヤ内側から外側へ巻き上げ、インナーライナー層7の少なくとも一方の巻き上げ部分7aをベルト層6と重なる位置まで延在させる。
【選択図】 図1
Description
各試験タイヤを標準リムに組み付けて試験車両に装着し、空気圧を200kPaとし、テストドライバーによるフィーリング評価を行った。評価結果は、従来例を100とする指数にて示した。この指数値が大きいほど操縦安定性が優れていることを意味する。
