カーカスバンドをビードコアの周りに巻き返すにあたり、カーカスバンドとビードフィラーとの圧着力を高め、残留エアを効果的に排除することができるタイヤの成型方法および成型ドラムを提供するものであり、円筒状をなすグリーンケースを成型ドラムの外周側に配置し、その成型ドラムによりビードコアの拘束下で両ビードコアを相互に近接変位させながら、グリーンケースの中央部分を半径方向に膨出変形させて、ベルトトレッドバンドの内周面にそのグリーンケースを圧着させ、その後の、カーカスバンドの両端部分の、ビードコアの周りへの巻き返しにあたり、カーカスバンドを、ビードコアおよびビードフィラーとともに、カーカスバンドの内周側に配設した剛性支持部材に押圧する。
