Anti-skid system

An anti-sliding system for a vehicle wheel comprising a rolling track, apt to be arranged between the ground and the tread of said wheel, and a retaining arrangement apt to constrain said rolling track to the wheel, the system passing from an unextended stationary condition to a maximum-extension condition during the mounting and then to a tensioning condition when steadily mounted on the wheel, the system furthermore comprising at least a return device consisting of superelastic material, embedded either in said rolling track or in said retaining arrangement in positions in which it undergoes deformation in said maximum extension condition.
