A refinement in the pneumatic tires for vehicle wheels to make them suitable for the travel on ice and snow, essentially characterized by the fact that in the central part of the bearing area of the cover there is a groove whose width is comprised between 1/6 and 1/3 of the total width of such an area in which a bearing ring, separately vulcanized, is movably housed, provided on its back with textile or metal reinforcing elements arranged in a preferably longitudinal direction, whose diameter internal is less than that which corresponds to the bottom of said groove with the tire being inflated, and the degree of elongation of said reinforcements being less than that of the textile materials used in the constitution of the resistant elements of the tire.
