A method includes a tubular carcass with core forming process (K1), a rubber laminate forming process (K2), and a tubular base tire forming process (K4). The forming process (K1) of forming a tubular carcass with bead core (6R3) on a first drum (20) comprises a tubular carcass forming step (K1a) to form a tubular carcass (6R2) by butt-jointing circumferential end faces of a carcass ply member (6R1) wound singly on the first drum (20), and a bead core joining step (K1b) to form integrally by diameter-expanding and pressing the tubular carcass (6R2) against the bead cores (5) outserted on the radially outer side. In the forming process (K2), rubber members for base tire (Ga) including an inner liner rubber member (G10a) are wound on a second drum (27) so as to form a rubber laminate (11). In the forming process (K4), the tubular carcass with bead core (6R3) is transferred from the first drum (20) to the second drum (27), and the rubber laminate 11 is pressed against the tubular carcass with bead cores (6R3) so as to form a tubular base tire (35).
