A pneumatic tire and process for manufacturing the same enable, in the use of a film of a thermoplastic resin or a thermoplastic elastomer composition obtained by blending an elastomer in a thermoplastic resin as an air permeation preventive layer, formation of the air permeation preventive layer excelling in gas barrier performance, and molding of the tire through a simple molding operation without generating any unnecessary scraps. For the pneumatic tire, a cylindrical molded article composed of a film of a thermoplastic resin or thermoplastic elastomer composition obtained by blending an elastomer in a thermoplastic resin is crushed into a sheet-like laminate; and the laminate is used as the air permeation preventive layer. In the manufacturing operation, the sheet-like laminate is wrapped around a making drum so that an unvulcanized tire having the sheet-like laminate as an air permeation preventive layer is molded, and the unvulcanized tire is vulcanized.
