ABSTRACT:
A method of manufacturing pneumatic vehicle tires, the tires having a carcass which extends between two bead rings and a breaker arranged between the carcass and a tread, wherein the respective tire blank is built up using exclusively non-metallic components, and wherein, in the course of vulcanization and shaping which takes place under the action of heat and pressure, at least a part of the thermal energy that is required is introduced into the tire in the form of microwave energy. In order to improve the tire quality and in particular to avoid defects as a result of incorrect thermal treatment, the temperature which prevails in the tire is controlled in different tire regions in dependence on the temperature development and differently for different tire regions.
