Abstract
Abstract A method of producing tires with a belt located between tread surface and carcass and provided with intercrossing strength members, according to which, the belt with tread strip on one hand, and the carcass on the other hand, are made separately, whereupon the belt and the carcass are united to each other by curving the carcass into the belt while enlarging diameter of the belt to approximately the extent to which the tire has to be enlarged in diameter during its vulcanization.
