The invention discloses a tire making machine. The tire making machine comprises a machine frame, an upper pressing roller and a lower pressing roller, wherein the upper pressing roller and the lowerpressing roller are rotationally connected to the machine frame; one side of the machine frame is provided with a slide rod, the slide rod is slidably connected with a pair of slide sleeves, the slidesleeves are provided with slide seats abutting against the side walls of the upper pressing roller and the lower pressing roller, and the slide seats are provided with guide plates abutting against the outer wall of the upper end of the upper pressing roller; the side, away from the slide rod, of the machine frame is provided with a supporting frame, a supporting seat is hinged to the supportingframe, and the supporting frame is internally provided with a first air cylinder driving the supporting seat to rotate; a supporting rod is hinged to the supporting seat, and the supporting seat is provided with a second air cylinder driving the supporting rod to rotate; and the supporting rod is horizontally and rotationally connected with a rotary shaft, and the rotary shaft is provided with a rotary roller used for pressing the outer wall of the upper pressing roller. The tire making machine has the following advantages and effects that by arranging a high-automation winding mechanism, intermediate tire rubber and surface layer rubber are wound around the outer wall of a steel ring inner tire in sequence, the machining process of a tire bead is achieved, the labor intensity of workers is relieved, and the working efficiency is improved.
