Abstract

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 in the tread band a central annular portion and a pair of lateral annular portions arranged on opposite sides with respect to said central annular portion. The central annular portion 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 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 central block comprises opposite axially outer faces (35, 65) inclined with respect to the equatorial plane by a predetermined angle and opposite circumferentially outer faces (32, 62) having an axially central portion (32a, 62a) perpendicular to the equatorial plane and opposite axially outer portions (32b, 62b) inclined with respect to a plane orthogonal to the equatorial plane by a predetermined angle different from 90°. Each lateral annular portion comprises a plurality of circumferentially consecutive lateral blocks (80, 90) separated from one another by a respective lateral transversal groove (85, 95). Each lateral block comprises an axially inner face (83, 93) having at least one part inclined with respect to the equatorial plane. At least one inclined part (83a, 83b) of at least some of the lateral blocks (80) is substantially parallel to at least one of said axially outer faces (35, 65) of said central block (30, 60).
