Method for manufacturing pneumatic tire

A method for manufacturing a pneumatic tire, comprising:

• lap splicing end parts of a laminate sheet comprising a thermoplastic sheet obtained from a thermoplastic resin or a thermoplastic resin composition, the composition comprising a thermoplastic resin blended with an elastomer, and the thermoplastic sheet being laminated with a rubber that undergoes vulcanizing adhesion with the thermoplastic resin or the thermoplastic resin composition;
• and
• sharpening distal end parts of the thermoplastic sheet obtained from the thermoplastic resin or the thermoplastic resin composition with a thermal treatment after the thermoplastic 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 tire vulcanization molding, before the lap-splicing, and before lamination of the thermoplastic sheet with the rubber, wherein the sharpening has a relationship in which a thickness T (mm) at a position at a distance inward by a length of (t×⅓) from the distal end of the thermoplastic sheet obtained from the thermoplastic resin or the thermoplastic resin composition satisfies the equation 0.1t≤T ≤0.8t, where
• t:
• average thickness (mm) in the tire circumferential direction of a portion not subject to the sharpening of the thermoplastic sheet obtained from the thermoplastic resin or the thermoplastic resin composition of a thermoplastic resin blended with an elastomer, and
• T:
• thickness (mm) at a position at a distance inward by a length of (t×⅓) from the distal end of the thermoplastic sheet obtained from the thermoplastic resin or the thermoplastic resin composition of a thermoplastic resin blended with an elastomer.
