To reduce the manufacturing cost of a tire that uses a thermoplastic material for a tire frame member.A tire manufacturing method includes: using a thermoplastic material to form a tire frame member (12); disposing cushion rubber (14) (unvulcanized rubber) on an outer peripheral surface of the tire frame member (12); further disposing vulcanized or semi-vulcanized tread rubber (16) on a tire diameter direction outer side of the cushion rubber (14); covering the tread rubber (16), the cushion rubber (14), and at least the tread rubber (16) side of the tire frame member (12) in an envelope, so as to push the tread rubber (16) against the tire frame member (12) side, to configure a provisionally assembled article; and accommodating the provisionally assembled article inside a container and heating the inside of the container to perform vulcanization to thereby adhere the tread rubber (16) to the tire frame member (12).
