Abstract

PURPOSE: To prevent the generation of oozing out portion of a cushion rubber at a peripheral rim portion of a tread base portion and improve a beautiful appearance by a method wherein a tread is bonded on a base tire through a green cushion rubber for bonding, successively, they are molded integrally under pressurizing and heating.
CONSTITUTION: An angle α between a vertical line X-X, drawn from a shoulder edge SE of a tread 2 vulcanized beforehand to a tread base portion 6, and a buttless portion 7 is specified to be 5°W20° and a point P on the buttless portion 7 is defined to be as high as 2W20mm from the base portion 6 while a base portion of the buttless portion 7 is drawn by a line connecting the point P and a point γ having a distance l(=2W20mm) from an intersecting point Q of the base portion 6 and the buttless portion 7. The tread 2 thus formed is bonded on a base tire 1 through a bonding cushion rubber 3 and is vulcanized and molded under being pressurized and heated to obtain a desired reformed tire.
