Abstract

A tyre for vehicle wheels comprises a tread band on which a radially external tread surface and a tread pattern are defined; the tread band comprising: a central region of the tread band, extending circumferentially about an equatorial plane of the tyre over at least 30% of an effective width of the tread band; a first and a second shoulder region extending, on opposite sides of the central region, each over at least 20% of the effective width of the tread band; the tread pattern, on the first and second shoulder regions and the central region, comprises transverse grooves comprising a bottom and a pair of opposed lateral walls. These lateral walls extending from the bottom towards the tread surface with a first inclination, and joining to the tread surface by chamfers having a second inclination greater than the first inclination relative to the radial direction.
