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.
Abstract:
The invention relates to a spike arrangement that comprises a holding element (12) introducible into an embedding opening of a running surface (10), in particular of a tire, which element forms a receptacle (14) for an anti-skid stud (16) projecting from the running surface (10) of the tire. According to the present invention, the holding element (12) is made at least in part of magnesium or a magnesium alloy. A method for manufacturing a spike arrangement of this kind is furthermore indicated.

Abstract:
A device for inserting or moulding into a tire tread to increase traction and stabilize the tread comprising an elongated body having an end surface and installed in the tire so that the end surface is spaced inwardly of the tread surface in a manner defining a recess. As the tire moves along a supporting surface such as a road, the portion containing the device is brought into and out of maximum stress thereby varying the volume of the recess in a manner creating suction therein which increases traction between the tire and road. The device is formed of material having wear characteristics substantially similar to the tire material, for example thermosetting plastic material which preferably is filled with iron powder. The device has a frusto-conical body terminating in the end surface and having a relatively larger diameter base portion at the opposite end for proper securement in the tire.
