Abstract: A pneumatic tire having a radial carcass comprises two reinforcing layers, of metallic cords, one over the other, in each sidewall. A flipper may be embedded in the upper portion of the sidewall. The flipper is formed by the turned up end of the innermost layer of the sidewall around the second layer of the sidewall reinforcement.

Abstract: A pneumatic tire for vehicle wheels having a radial carcass is provided with an annular reinforcing structure inserted between the carcass and tread. The annular reinforcing structure is substantially inextensible and has a width which is at least as wide as the tread. The tire is provided in each sidewall with a mixed textile-metallic reinforcement member which has a strip which forms two skirts of different widths. The cords of the skirts are inclined with respect to the radial direction of the carcass cord. A second strip of metallic cords inclined with respect to the radial direction and narrower than the longer skirt is inserted between the skirts to the folded-edge. The larger skirt is disposed axially outside of the carcass ply and its turned over portion and radially extended from the bead zone to the tire's shoulder. The smaller skirt extends radially towards the inside from the shoulder to a point disposed in the sidewall, to a height between 66% and 20% of the tire's section height.
