refinement the radials with structure of tightening in the hips

摘要

Subject matter of the invention is a tyre for vehicle wheels, comprising a radial carcass, a tread and an annular reinforcing structure inserted between the said carcass and said tread and being substantially circumferentially inextensible and at least as wide as the tread. For providing favorable transversal and circumferential rigidity in the zones of the sidewalls of the type - particularly of a high speed tyre - there are arranged in each sidewall a mixed textile-metallic reinforcement (14), comprised by two skirts (15, 16) of textile cords having different widths, the cords of said skirts being inclined with respect to the radial direction of the carcass cords, and by a strip (17) of metallic cord also inclined with respect to said radial direction and having a lesser width to that of said greater width skirt (15) and inserted in between said skirts (15, 16).
