<p>A method for improving the control of the road-holding of a tyre (1, 100), which includes a tread band (2), on which there is defined a central region (6) which is developed symmetrically about an equatorial plane (M) of the tread band and a pair of shoulder regions (7) which are axially opposite the central region, comprises: - providing respective pluralities of shoulder blocks (11), central blocks (10) and intermediate blocks (12) which are arranged in succession along the circumferential development of the shoulder region and the central region, - configuring the shoulder blocks (11) in order to obtain shoulder regions (7) having values of specific lateral rigidity which decrease with a reduction in the distance from the equatorial plane (M) starting from a maximum value in the region of an axial end (4a, 4b) of the tread band, - configuring the central blocks (10) and the intermediate blocks (12) in order to obtain a central region (6) having values of specific lateral rigidity which increase with an increase in the distance from the equatorial plane starting from a minimum value in the region of the equatorial plane, and less than the values of specific lateral rigidity of the shoulder regions, so as to determine a progressive trend of the values of specific lateral rigidity between the axial end and the equatorial plane, wherein the minimum value of specific lateral rigidity is between 65% and 85% of the maximum value of specific lateral rigidity.</p> |
