摘要

When manufacturing a tire having letters or lines of the first color on at least one side wall part, the second color side wall rubber and the first color side wall rubber are respectively formed on the side surfaces of the carcass member formed in a toroidal shape. A continuous second-color rubber ribbon and a continuous first-color rubber ribbon are wound and pasted multiple times, and then a second-color cover rubber is wound around the side wall rubber around the rubber sheet in an annular shape. By pasting and molding green tires, it is easy to change the size and efficiently produce tires of other types without requiring a large extruder, and the shape and dimensions of each member are highly accurate It is also excellent in terms of uniformity and tire balance, and the outline of the first color letters or lines is To provide a manufacturing method capable of producing tires with no problem appearance and cut.
