METHOD FOR IMPROVING THE PERFORMANCE OF A STUDDED TYRE AND STUDDED TYRE PRODUCED ACCORDING TO THIS METHOD

What is described is a method for improving the performance of a studded tyre provided with a tread band (2) in which is formed a plurality of holes (4) in which a corresponding plurality of studs (10) are housed by engagement, each of these comprising a base (13) housed in a radially internal position in one of the holes. This method comprises opposing the oscillatory movements of the stud (10) in the hole (4) about an axis substantially parallel to an axis of rotation (X) of the tyre, by providing, at the base (13), a front abutment region (16a) and a rear abutment region (17a) which are opposite each other, thereby providing mutual abutment between the base (13) and the tread band (2), in which provision is made to configure the base (13) asymmetrically with respect to a radial plane (R) of the tyre passing through a longitudinal axis (Z) of the stud, in such a way that the front abutment region (16a) is larger than the rear abutment region (17a), in order to increase the retaining action of the tread band on the studs.
