In a method for manufacturing a pneumatic tire, molding of a green tire has (a) an assembly step of bonding an inner liner (2) and an unvulcanized rubber sheet (3) with end portions thereof (2a, 2b; 3a, 3b) in a width direction being displaced from each other by 50 mm to 500 mm in the width direction to manufacture a laminate, (b) cutting the laminate to have a constant length corresponding to a width of a drum (5) to manufacture a cut sheet (4), and (c) a joining step of winding the cut sheet (4) on entire circumference of the drum (5) such that a cut surface thereof extends in a circumferential direction of the drum (5) and the inner liner (2) is disposed on an inner surface side, and joining the end portions (2a, 2b) of the inner liner (2) and joining the end portions (3a, 3b) of the unvulcanized rubber sheet (3) such that positions of the joined end portions are displaced by a constant distance.
