Patent ID: 7484543

Claim:
A tyre for a motor vehicle, comprising: a tread, the tread defining a longitudinal direction and a lateral direction transverse to the longitudinal direction; and two shoulders; wherein the tread comprises: a first circumferential row of blocks disposed between first and second circumferential grooves, wherein each of the blocks is delimited by a section of the first circumferential groove and by first and second transverse grooves that extend from the first circumferential groove and terminate at a first common vertex spaced from the second circumferential groove, wherein the second transverse groove delimits a first one of the blocks and is separated from the first transverse groove that delimits a circumferentially adjacent block by a solid tread portion, wherein the first common vertex is separated from the second circumferential groove by a continuous circumferential tread rib, wherein the solid tread portion extends from the first circumferential groove to the continuous circumferential tread rib, and wherein the solid tread portion forms a single body with the continuous circumferential tread rib, spacing the first block and the circumferentially adjacent block from each other; and a second circumferential row of blocks disposed between the second circumferential groove and a third circumferential groove, wherein each of the blocks of the second circumferential row of blocks is delimited by a section of the second circumferential groove and by third and fourth transverse grooves that extend from the second circumferential groove and converge and terminate at a second common vertex, wherein at least one of the first and second transverse grooves comprises an increasing width in a direction from the first common vertex toward the first circumferential groove, and wherein the first and second transverse grooves and the third and fourth transverse grooves extend from the respective first and second circumferential grooves in the same lateral direction of the tread.
