Patent ID: 6923231

Claim:
A tyre for vehicle wheels provided with a tread pattern, wherein the tread pattern comprises: at least one continuous central circumferential groove straddling an equatorial plane of the tyre; at least two continuous lateral circumferential grooves having median planes substantially parallel to the equatorial plane of the tyre; and a plurality of transverse grooves; wherein the at least one central circumferential groove, the at least two lateral circumferential grooves, and the plurality of transverse grooves delimit at least four circumferential rows of blocks, two central rows and two shoulder rows, each block of the central rows being defined by a plurality of sides and at least four vertices, a pair of front vertices and a pair of rear vertices, in relation to a predetermined running direction of the tyre; wherein the blocks of the central rows comprise a water-draining first transverse notch having a first terminal end inside a respective block of the central rows and a first starting end communicating with the at least one central circumferential groove, wherein the first transverse notch extends beyond a longitudinal median plane of a respective central row of blocks, wherein a first ratio of an axial width of the blocks of each central row to an overall axial width of a tread band, measured between shoulder ends of the tyre, is not less than 0.18:1, wherein the transverse grooves delimiting the blocks of the shoulder rows comprise, at least in a vicinity of a closest lateral circumferential groove, portions inclined in relation to the equatorial plane of the tyre in a direction opposite to an inclination of the transverse grooves delimiting the blocks of a closest central row, wherein the blocks of the central rows comprises a second transverse notch extending between a second terminal end inside a respective block and a second starting end in a position opposite the second terminal end, wherein respective first and second transverse notches are substantially perpendicular to each other, wherein the first transverse notches have a width between 2 mm and 7 mm, and wherein the transverse grooves delimiting the blocks of the central rows have a width between 2 mm and 7 mm.
