ABSTRACT:
A belt for a belted tire with an inner continuous layer and with an outer layer divided into two marginal sections and an intermediate section. The strength carriers of the inner belt layer extend over the width thereof in one direction and at a first angle with regard to the circumferential direction of the belt. The strength carriers of the intermediate section of the outer layer extend only over the width of the intermediate section and at the same angle as the first mentioned angle but in an opposite direction to the strength members of the inner belt layer. The strength members of the marginal sections extending in the same direction as the strength members of the intermediate section but at a smaller angle with regard the circumferential direction of the belt than the angle at which the strength members of the outer belt layer extend. The marginal areas of the inner belt layer as well as the marginal sections of the outer belt layer folded over the adjacent areas of the intermediate belt section of the outer belt layer. Prior to applying the belt to the carcass of a raw tire, the diameter of the belt is extended by from 5 to 25%.
