Abstract
The invention related to a method for producing a rim for a pneumatic tire. A rim base with a rear rim flange is produced from a ring-shaped blank by exerting pressure. Said rim base is then connected to a bowl of a rim at the side thereof facing away from the rear rim flange. In order to produce said rim base, the blank is inserted into a compression mould which is embodied as a cavity and is pressed against the at least partially contoured interior of the compression mould by means of at least one compression roll.
