A refinement in the tires for vehicle wheels, whose tread is provided with a stiffness-resistant structure, said structure being formed by at least two strips of cord fabric whose strings are inclined with respect to the equatorial plane, each of said folded strips so as to be bent and form a pair of layers, the bending lines of the two strips facing the two edges of the tread and constituting the edges of the stiff structure, the free end being strip superimposed on the free end of the other strip in the central zone of the tread, essentially characterized by the fact that the area in which the free ends of the straps are superimposed has a width no greater than 2/3 of the the total width of the resistant structure and the fact that the angle that the cord of a strip forms with the equatorial plane is greater than the angle that with the same plane they form the cord of the other strip, being the difference between the absolute value of said two angles not inferior to 10º.
