Abstract

　タイヤのユニフォミティーを向上させる。 　成形フォーマ上に巻回された円筒状プライ６Ａ１のうちで、ビードコアセット位置Ｐよりもタイヤ軸方向内側のプライ内側部分６Ａ１ａ、及び／又はタイヤ軸方向外側のプライ外側部分６Ａ１ｂの上に、ゴムストリップ２０を周方向かつ螺旋状に重ねて巻き付けることによりビードエーペックス形成用のストリップ巻回体２１を形成するストリップ巻き付け工程Ｓ３を有する。又前記円筒状プライ６Ａ１のプライ内側部分６Ａ１ａをトロイド状に膨張させる膨張工程Ｓ４と、前記円筒状プライ６Ａ１の前記プライ外側部分６Ａ１ｂを前記ビードコア５の廻りで折り返し、トロイド状のプライ内側部分６Ａ１ａとの間でストリップ巻回体２１を挟み込んで互いに接合する接合工程Ｓ５とを具える。
