Abstract

A method and apparatus for vulcanizing pneumatic vehicle tires having heads that in the mounted state are disposed on the radially inner periphery of a rim. In order for such tires to achieve a satisfactorily contoured vulcanization, and in order at the same time to produce sealing surfaces with great precision, the tire is vulcanized with its beads in their operating position. During the vulcanization, the radially outwardly disposed surfaces of the tire beads are shaped with the aid of rigid, one-piece, shaped molding rings.
