A tire building machine and method characterized by the employment of a rigid annular bead support at each end of and coaxial with the axis of a tire building drum for holding a tire bead in round and centered to the drum axis during bead placement, after bead placement and during a subsequent ply turn-up operation. The bead support preferably is in the form of a precision machined register ring preferably supported independently of the drum and having a radially outer bead support surface which extends slightly axially beyond a shoulder end face of the drum in radially inwardly offset relation to such end face. During bead placement and/or limited axial outward movement of the register ring, the register ring serves to wipe and firmly stitch interposed ply material to the inner diameter of the tire bead. During such wiping action, the bead may be axially held in place by an inflating turn-up bladder or by a bead setter utilized to set the bead at the drum end.
