Abstract

A pneumatic tire is formed by winding a sheet member (A) and a sheet member (B) onto a molding drum and molding a cylindrical body. A laminate body (M) in which the sheet member (B) is layered in advance on the outer periphery of the sheet member (A) is wound onto a molding drum (), the tack value of a material (a) constituting the sheet member (A) being smaller than the tack value of a material (b) constituting the sheet member (B), the length of the sheet member (A) being configured so that a starting end (As) of winding on the molding drum () and an ending end (Ae) of winding do not overlap, and the length of the sheet member (B) being configured so that the ending end (Be) of winding extends longer in the circumferential direction than the ending end (Ae) of winding of the sheet member (A).
