A tyre for vehicle wheels comprising a tread band (2), upon which there are defined a plurality of first transverse grooves (30) and a plurality of second transverse grooves (60) slanted in a discordant manner with respect to the first transverse grooves (30).Each first transverse groove (30) comprises a first portion (33) extended from a first axially external end (31) and slanted relative to said circumferential direction by a first angle (A), and a second portion (34) extending from the first portion (33) and slanted relative to said circumferential direction by a second angle (B) smaller than the first angle (A).Each second transverse groove (60) comprises:- a first portion (62) extended from a first axially internal end (61) and slanted relative to the circumferential direction by a third angle (C), differing from the first angle (A) by less than 15°,- a second portion (63) extending from the first portion (62) and slanted relative to the circumferential direction by a fourth angle (D) smaller than the third angle (C) and differing from the second angle (B) by less than 15°, the second portion ending in the second portion (34) of a corresponding first transverse grooves (30), as well as- a third portion (64) extending from the second portion (34) of the corresponding first transverse grooves (30) and parallel to the second portion.The first end (61) of the second transverse groove (60) and the first end (31) of the corresponding first transverse groove (30) are substantially aligned along an axial direction of the tyre or, at most, are offset by less than 20 mm.There are identified a first group of second transverse grooves (60), comprising at least 10% of the second transverse grooves, wherein the third portion (64) is substantially aligned with the second portion (63) and a second group, complementary to the first group, wherein the third portion (64) is not aligned relative to the second portion (63).
