<p>Provided is a method of producing a pneumatic tire, which prevents occurrence of blisters caused by trapped air when a thermoplastic resin film is used as an air permeation prevention layer, and particularly, a method suitable for producing a heavy-duty pneumatic tire. The method of producing a pneumatic tire includes: wrapping a thermoplastic resin film 6 around a making drum 20; winding an unvulcanized tie-rubber sheet 7 on the thermoplastic resin film 6; splicing a winding start portion and a winding end portion of the tie-rubber sheet with each other; and thereafter winding a carcass layer on the tie-rubber sheet 7. In the method, a splice of the tie-rubber sheet is made to be a butt-splice, and an unvulcanized auxiliary rubber sheet 9 is interposed between the tie-rubber sheet 7 and the thermoplastic resin film 6, along a joint 7c of the butt-splice.</p> |
