Abstract

IMPROVED RADIAL TIRE FOR MOTOR VEHICLES A pneumatic tire having a radial carcass is provided with a reinforcing structure between the carcass and tread having first and second layers of metallic cords having an ultimate elongation of about 3%. The cords of the first and second layers are disposed parallel to each other and at angles of about 5.degree. to about 30.degree. with the axis of the tire body with the cords in one layer crossing the cords of the other layer. A third layer of metallic cords having an ultimate elongation of from about 4% to about 8% is disposed radially outwardly over the first two layers. The cords in the third layer are wound about the carcass in a plane which is substantially parallel to the longitudinal direction of the tire. The resulting assembly of layers provides a reinforcing structure which is adapted to withstand the tension stresses exerted on tires used on heavy vehicles such as buses and trucks even at high speed, giving also high steering characteristics to the tire.
