A tyre for vehicle wheels comprises a tread band including a plurality of blocks and grooves that define in the tread band a void/solid ratio comprised between 0.4 and 0.65 and that form a tread pattern which is symmetrical with respect to an equatorial plane (X-X) of the tyre. The tread pattern includes a pair of circumferential grooves (20) arranged on opposite sides with respect to the equatorial plane and which define a central annular portion of tread band and a pair of lateral annular portions of tread band arranged on opposite sides with respect to said central annular portion. The central annular portion of tread band comprises a plurality of circumferentially consecutive central blocks (30, 60) arranged astride of the equatorial plane and having a maximum width equal to, or greater than. 50% of a radial section maximum width of the tyre. The central blocks (30, 60) are separated from one another by a respective central transversal groove (45, 50) having a circumferential length less than that of a circumferentially adjacent central block (30, 60). Each lateral annular portion of tread band comprises a plurality of circumferentially consecutive lateral blocks (80, 90) separated from one another by a respective lateral transversal groove (85, 95).
