A tire building method and a stitcher device therefore, which are aiming for achieving reliable pressing for bonding between a plurality of tire members all over outer face of the tire members, without forming a void between them, even though the outer face of the tire members have ups and downs, so as to curb strain in a carcass cord and to improve process efficiency. The method comprising: laying one or more of the tire members on a rotary support body such as a building drum; and press-contacting a press-contact part of a stitcher device on said one or more of the tire members on the rotary support while the rotary support being rotated, so as to bond together said one or more of the tire members; said press-contact part being a pneumatic-tire roller maintained with a certain level of inner pressure.
