ABSTRACT:
A tire for a wheel of a vehicle includes a carcass, a belt structure, and a tread. The tread pattern includes at least two circumferential grooves and at least three circumferential ribs. The grooves include a zigzag configuration and a shape repeated according to a circumferential pitch. Within a single pitch, each groove includes at least two directions different from a circumferential direction of the tire, generating at least two ground-gripping fronts in each of two rotation directions of the tire, and at least one blind transverse cut extending from opposite sides of the groove, generating a third ground-gripping front. Ends of the blind transverse cuts are positioned on planes parallel to each other and to an equatorial plane of the tire. The first plane and the second plane delimit a continuous portion of at least one of the circumferential ribs. The continuous portion includes a constant axial width.
