Abstract: A method, device, system and a computer product for producing a pneumatic tire are disclosed. The method comprising placing the inner layer and the carcass ply on a tire building drum and on a supporting ring with a bladder, moving core fixings radially to a larger radius, where the radius to which the core fixings are moved is greater than the unexpanded radius of the tire building drum, moving the core fixings radially to a smaller radius, forming tire shoulders by expanding the tire building drum, setting a bead core on the carcass ply at the drum shoulder, fixing the bead core by the radially movable core fixing, turning up the carcass ply and the inner layer by a bladder.
