<P>PROBLEM TO BE SOLVED: To provide a tire manufacturing device capable of efficiently manufacturing a good quality tire where, when the diameter of an annular tread is increased, the diameter of the tread is increased uniformly in a circumferential direction, and when the tread is mounted to a base tire, the tread is prevented from being mounted to the base tire while being displaced therefrom in a width direction, and to provide a tire manufacturing method. <P>SOLUTION: The tire manufacturing device where the annular tread is mounted to an outer peripheral surface of the base tire includes: a drum to which the base tire is affixed; a plurality of holding means each having a holding surface for holding the outer peripheral surface of the annular tread; a moving means for moving the holding means along the central axis of the base tire; a sealing means for sealing one opening of the annular tread; and an air supply means for supplying air to a space surrounded by the annular tread and the sealing means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
