摘要： 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.

摘要： The present invention relates to a tire designed to be fitted on the driving axles of a motor vehicle for medium or heavy load. This tire is provided with a tread comprising a plurality of full-depth transverse grooves and four circumferential series of inclined grooves and four circumferential series of inclined incisions which delimit five circumferential rows of blocks, namely two axially outer rows, two intermediate rows, and one central row lying essentially across the equatorial plane.Each transverse groove extends across the whole width of the tread, and consists of a central portion, located between a pair of consecutive blocks of the central row, and a pair of lateral portions, located between pairs of consecutive blocks of the intermediate and shoulder rows.The two lateral portions of each transverse groove are staggered circumferentially with respect to each other and penetrate into the body of the central row of blocks. The central portion of the transverse groove has a depth of 3 mm, while the depth of the incisions located between the shoulder blocks and the intermediate blocks is less than the depth of the inclined incisions located between the intermediate blocks and the central blocks.

摘要： A tire (1) having low rolling resistance, in particular for driving wheels of heavy vehicles, comprises a tread (14) provided with a plurality of transversal grooves (20) pitchwise spaced from one another and extending in a direction substantially perpendicular to the rolling direction of the tire (D). The grooves (20) have a reduced depth and are provided with respective slits (24), extending from a bottom portion (21) thereof; as such, they contribute to impart to the tire (1) both the desired low rolling resistance and an adequate traction characteristics during straightaway running.

摘要： A tire tread band for medium/heavy duty motor-vehicles having circumferential grooves confining three pairs of respectively center, intermediate and shoulder ribs. Respective tread blocks are defined along the center and intermediate ribs and they are confined by transverse cuts. The center cuts impart a cusp-shaped end conformation and a hollow-shaped end conformation to the respective blocks, and the shapes of said end portions mutually match. The intermediate cuts run in the linear extension of the center cuts to give the respective blocks a rhomboidal configuration. The tire can be alternately associated with a driving axle or a driven axle, by merely reversing its direction of rotation, so that the following results are selectively achieved: an increase in the traction capability by the intermediate blocks or an increase in the directional capability as a result of the mutual wedging between the center blocks at the ground-contacting area.
