[Problem] It is a manufacturing method for a pneumatic tire 1 having a green tire formation process for applying an unvulcanized carcass ply 6A to the outer surface of a rigid core 20. The green tire formation process includes a process for continuously forming a plurality of strip-shaped sheet-like first ply pieces 13 by cutting a long ribbon-shaped ply 12 along a ply-width direction sequentially from the leading end, a ply piece forming process for continuously forming a plurality of strip-shaped sheet-like second ply pieces 14, and a carcass forming process for forming the unvulcanized carcass ply 6A by the use of the first and second ply pieces 13, 14. The second ply pieces 14 are not overlapped with the first ply pieces 13 at the tire equator Co, but directly overlapped with the first ply pieces 13 in the radially inner end portions 14i of the second ply pieces 14.
