Abstract
A process for manufacturing radial type motor vehicle pneumatic tires is provided in which an annular reinforcing structure is disposed on a toric carcass. The reinforcing structure is built up of two layers of metallic cords crossed with each other, and an additional third layer of heat shrinkable textile cords that form, with the longitudinal direction of the tire, an angle which is not zero and is a smaller angle than that of the underlying cords. The third textile layer is applied by butt-joining its respective opposite ends along a straight line parallel to the metallic cords of the underlying metallic layer.
