- 成形ドラムの外周面にインナーライナを巻き付けるとともに、インナーライナの幅方向両端側に帯状の補強材を巻き付けて補強層を形成し、インナーライナ及び補強層にカーカス材を巻き付けることにより、径方向に膨出させる前の内周側グリーンタイヤを成形するタイヤ成形方法において、
補強層に対応する幅方向両端側が幅方向中央側よりも外径の小さい小径部からなる成形ドラムを用い、
カーカス材の少なくとも幅方向中央側に空気抜き孔を形成し、
カーカス材及び補強層を幅方向両端側から幅方向中央側に向かって順次補強層及びインナーライナ側に圧着させ、
成形ドラムの幅方向中央側と小径部との半径の差が補強層の厚さの70%から90%になるように成形する
ことを特徴とするタイヤ成形方法。
