description A tyre (100) for vehicle wheels has a tread (106) comprising a central annular portion astride an equatorial plane and two shoulder annular portions, located on axially opposite sides with respect to the central annular portion. The central annular portion is separated from each shoulder annular portion by a respective first circumferential groove (201), the central annular portion comprises at least one second circumferential groove (202), at least one of the first and the second circumferential grooves (201, 202) has a radial depth D not smaller than 8 mm and a cross section A expressed in mm2, wherein, defining A1 the cross section of a radially outermost portion of a circumferential groove extending over a depth D1 equal to 50% of the radial depth D, at least one of the first and the second circumferential grooves (201, 202) is formed so that A1 > 0,5A and that A/D has a numerical value between about 0,5 and about 7.
