Abstract
Provided is a method for manufacturing a pneumatic tire capable of easily and appropriately winding a sheet lamination body formed by a resin film and an unvulcanized rubber sheet around a shaping drum. In the method for manufacturing a pneumatic tire including conveying a sheet lamination bodyto a shaping drum, and winding the conveyed sheet lamination bodyin a position that a resin filmis located on the inner side while causing an outer peripheral surface of the shaping drumto retain the conveyed sheet lamination body, a resin film protrusion portionis formed by making a leading edgeof the resin filmprotrude toward a downstream side in a conveying direction A than the leading edgeof the unvulcanized rubber sheetas viewed in the conveying direction A at the time of attaching the resin filmon a surface of an unvulcanized rubber sheet, and the outer peripheral surface of the shaping drumis caused to retain in advance the resin film protrusion portionto wind the sheet lamination bodyon the outer peripheral surface of the shaping drum
