Tire designed to roll on ground that may be covered with ice, comprising: a tread made of at least one rubber compound and having a tread surface, a plurality of housings opening onto the tread surface via an orifice and containing a stud, the orifice having a maximum dimension D0 on the tread surface when the stud is in the housing; the stud comprising: a base, designed to anchor the stud in the tread; a tip, designed to project from the tread in order to come into contact with the ice; a body connecting the base and the tip, the body having an axis of symmetry; and a longitudinal axis passing through the axis of symmetry of the body; wherein the tread surrounding the stud forms an anchoring platform for the stud, this platform in turn being surrounded by a cavity opening onto the tread surface so that the volume of recess opening onto the tread surface in a radius greater than or equal to D0/2 and less than or equal to D0/2+2 mm about the longitudinal axis of the stud is less than or equal to 20 mm3; and the volume of recess opening onto the tread surface in a radius greater than or equal to D0/2+2 mm and less than or equal to D0/2+4 mm about the longitudinal axis of the stud is greater than or equal to 60 mm3 and less than or equal to 100 mm3.
