Tyre for vehicle wheels, comprising a tread band, on which there are defined: - a pair of axially opposite shoulder regions (7, 9); - a central region interposed between said shoulder regions and extending symmetrically relative to an equatorial plane for a width between 40% and 75% of the effective width of the tread band, the effective width of the tread band being the width of the radially outermost portion of the tread band, edge to edge, designed to get in contact with the ground, wherein, in each of said shoulder regions and said central region, are provided: - a plurality of main transverse grooves (30, 40, 50) slanted relative to a circumferential direction defined on said tread band, - a plurality of blocks in which a plurality of sipes are formed, characterised in that, in said central region, all said main transverse grooves (30, 40) are slanted relative to a circumferential direction in a concordant manner to one another and all said sipes are slanted in a concordant manner to one another and in a discordant manner with respect to said main transverse grooves wherein two transverse grooves, considered on a Cartesian plane positioned tangentially on the tread band, with the axis of the ordinates parallel to the circumferential direction and the axis of the abscissas parallel to the axis of the tyre, are slanted in a concordant manner when their trend is, for both, increasing or decreasing, and are slanted in discordant manner when their trend is increasing for one groove and decreasing for the other groove, and wherein a plurality of first main transverse grooves are provided in one of said shoulder regions and in said central region, each of which grooves comprises: - a first portion extending from said shoulder region towards the equatorial plane of said tyre, which first portion is slanted relative to said circumferential direction by a first angle and a second portion extending into said central region towards said equatorial plane as a continuation of said first portion which second portion is slanted relative to said circumferential direction by a second angle, that is smaller than said first angle. - a pair of axially opposite shoulder regions (7, 9); - a central region interposed between said shoulder regions and extending symmetrically relative to an equatorial plane for a width between 40% and 75% of the effective width of the tread band, the effective width of the tread band being the width of the radially outermost portion of the tread band, edge to edge, designed to get in contact with the ground, wherein, in each of said shoulder regions and said central region, are provided: - a plurality of main transverse grooves (30, 40, 50) slanted relative to a circumferential direction defined on said tread band, - a plurality of blocks in which a plurality of sipes are formed, characterised in that, - a plurality of main transverse grooves (30, 40, 50) slanted relative to a circumferential direction defined on said tread band, - a plurality of blocks in which a plurality of sipes are formed, characterised in that, in said central region, all said main transverse grooves (30, 40) are slanted relative to a circumferential direction in a concordant manner to one another and all said sipes are slanted in a concordant manner to one another and in a discordant manner with respect to said main transverse grooves wherein two transverse grooves, considered on a Cartesian plane positioned tangentially on the tread band, with the axis of the ordinates parallel to the circumferential direction and the axis of the abscissas parallel to the axis of the tyre, are slanted in a concordant manner when their trend is, for both, increasing or decreasing, and are slanted in discordant manner when their trend is increasing for one groove and decreasing for the other groove, and wherein a plurality of first main transverse grooves are provided in one of said shoulder regions and in said central region, each of which grooves comprises: - a first portion extending from said shoulder region towards the equatorial plane of said tyre, which first portion is slanted relative to said circumferential direction by a first angle and - a first portion extending from said shoulder region towards the equatorial plane of said tyre, which first portion is slanted relative to said circumferential direction by a first angle and a second portion extending into said central region towards said equatorial plane as a continuation of said first portion which second portion is slanted relative to said circumferential direction by a second angle, that is smaller than said first angle.
