The invention is in a drum and a method of using it whereby the components for making the stage - I carcass can be expanded substantially radially say between 25% and 35% of the drum radius to ensure that the side wall components extend generally in planes perpendicular to the drum axis during crowning and includes fillers fitted to or attached to the beads which can be substantially undistorted in those planes and will be similarly substantially undistorted in use at the vital area where a tire is in contact with the wheel rim.
