Abstract

　周方向補強層のエッジ部の疲労破断を抑制しながら、周方向補強層の拡幅を可能にし、かつ交差ベルト層のエッジ部におけるセパレーションを抑制することを可能にした空気入りラジアルタイヤを提供する。 　本発明の空気入りラジアルタイヤは、トレッド部におけるカーカス層の外周側に少なくとも２層の交差ベルト層を配置し、これら交差ベルト層の間に該交差ベルト層よりも幅が狭い少なくとも１層の周方向補強層を配置した空気入りラジアルタイヤにおいて、周方向補強層の幅方向の端末位置よりも外側では交差ベルト層を互いに離間させると共に、周方向補強層を破断伸びが異なる２種類のスチールコードから構成し、周方向補強層のセンター部分に破断伸びが相対的に小さいスチールコードを配置し、周方向補強層の両外側部分に破断伸びが相対的に大きいスチールコードを配置したものである。
