Suitable controls and adjustments are provided for moving the carriages symmetrically about the center line of the drum into precise positions for positioning the tire beads with precision over the ends of the drum and holding the tire beads in place during expansion of the drum. Pusher rings may also be provided on the carriages to assist in obtaining symmetrical movement of the ply turnup bladders for obtaining the same amount of stitching and turnup of the plies on both sides of the tire.
