ABSTRACT:
A method of manufacturing a tire comprises a first process including the steps of forming a carcass ply or the like to a cylindrical configuration, placing bead cores on the cylindrical carcass ply and then effecting assembly of a carcass ply-bead core structure. A second process of the method includes the steps of receiving the structure from the last step in the first process, effecting assembly of a cylindrical carcass layer and then deforming the latter into a trochoidal configuration to obtain a green tire, wherein the carcass ply located between both the bead cores on the structure is caused to expand either in the first process or in the second process. The structure is placed on a drum device in the second process, the bead cores are wrapped with the end portions of the carcass ply and then the green tire for the radial tire is assembled by attaching side wall members or the like. Further, according to other aspect of the present invention an apparatus for practicing the above-described method is also disclosed.
