Abstract
A method for manufacturing a pneumatic tire includes preparing a sheet made from a thermoplastic resin or a thermoplastic resin composition which is a blend of the thermoplastic resin and an elastomer, tip-sharpening end portions of the sheet to form sharpened tips, preparing a laminate by laminating the sheet and a rubber such that the rubber forms an inner layer with respect to the sheet, lap-splicing end portions of the laminate, which include the sharpened tips of the sheet, to form a lap splice portion, and curing and molding the laminate in which the lap splice portion is formed to form an inner liner layer of the pneumatic tire after the tip-sharpening of the end portions of the sheet.
