The present invention provides a method for manufacturing a pneumatic tire having an inner liner layer or a reinforcing sheet layer formed from a laminate sheet by lap-splicing the ends thereof. In the laminate sheet, a sheet obtained from a thermoplastic resin or a thermoplastic resin composition of a thermoplastic resin blended with an elastomer is laminated with a rubber. With the method, cracking and separation near the spliced region of the laminate sheet do not occur after beginning travel on the manufactured pneumatic tire. The method of the present invention is a method for manufacturing a pneumatic tire having a step of lap-splicing end parts of a laminate sheet in which a sheet obtained from a thermoplastic resin or a thermoplastic resin composition of a thermoplastic resin blended with an elastomer is laminated with a rubber that undergoes vulcanizing adhesion with the thermoplastic resin or the thermoplastic resin composition, wherein, after the sheet obtained from the thermoplastic resin or the thermoplastic resin composition is cut into lengths to be supplied to the lap-splicing step, and at a stage before a tire vulcanization molding step, distal end parts of the sheet obtained from the thermoplastic resin or the thermoplastic resin composition are sharpened with a thermal treatment. |
