Provided is a method for manufacturing a pneumatic tire in which opening failure is significantly reduced. The present invention is characterized by having a step for winding a sheet member (A) and a sheet member (B) onto a molding drum and molding a cylindrical body, a laminate body (M) in which a sheet member (B) is laminated in advance on the external periphery of a sheet member (A) being wound onto a molding drum (10), the tack value of a material (a) for forming the sheet (A) being smaller than the tack value of a material (b) for forming the sheet member (B), the length of the sheet member (A) being configured so that a starting end (As) of winding on the molding drum (10) and an ending end (Ae) of winding do not overlap, and the length of the sheet member (B) being configured so that the ending end (Be) of winding extends longer in the circumferential direction than the ending end (Ae) of winding of the sheet member (A), whereby the ending end (Be) of winding is superposed and joined on an outer diameter side of a starting end (Bs) of winding of the sheet member (B).
