Abstract

　１プライ構造で巻き上げ部をベルト層の端部と重なるように該ベルト層の下方域まで延在させたカーカス層を有する場合であっても、連続走行による操縦安定性の性能変化を抑制することを可能にした空気入りタイヤを提供する。本発明の空気入りタイヤは、一対のビード部間にタイヤ周方向に対するコード角度が７５°～９０°の範囲にある１プライ構造のカーカス層を装架し、トレッド部におけるカーカス層の外周側にベルト層を配置し、前記カーカス層を各ビード部に配置されたビードコアの廻りにタイヤ内側から外側へ巻き上げ、前記ビードコア上に配置されたビードフィラーを前記カーカス層の本体部と巻き上げ部とで挟み込むと共に、前記カーカス層の巻き上げ部を前記ベルト層の端部と重なるように該ベルト層の下方域まで延在させた空気入りタイヤにおいて、前記ビードフィラーのビードヒールからの高さを２５ｍｍ以下とし、該ビードフィラーの断面積を６５ｍｍ2 以下とし、該ビードフィラーを構成するゴム組成物の６０°Cでのｔａｎδを０．２０以下としたものである。
