Abstract
A tire manufacturing apparatus and a tire manufacturing method capable of efficiently manufacturing quality tire by uniformly expanding the diameter of an annular tread and mounting the tread on a base tire without axial deviation. The tire manufacturing apparatus for mounting an annular tread on the outer periphery of a base tire includes a drum for securing a base tire, a plurality of holding means each having a holding surface for holding the outer periphery 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 the opening on one side of the annular tread, and an air supplying means for supplying air into a space surrounded by the annular tread and the sealing means.
