摘要： A tyre for vehicle wheels comprises a tread band (1) having a tread band pattern (2) defined by at least two circumferential portions (3) disposed in axial side by side relationship, at least one of which has a first geometric module (4) repeated many times along the circumferential extension direction (X) of the tyre. The first geometric module (4) comprises at least two shoulder blocks (5) circumferentially aligned along a side edge (6) of the tread band (1) and bounded by grooves (7) oriented transversely of the circumferential extension direction (X) of the tyre, and an elongated ridge (8) bounded by two grooves (9) oblique to the circumferential extension direction (X) and divided into a plurality of intermediate blocks (10) with respect to the axial extension (Y) of the tread band (1), which are delimited by a plurality of cuts (11) substantially transverse to the elongated ridge (8).
