A tire for a motor vehicle includes a tread and two shoulders. The tread includes a first circumferential row of blocks disposed between first and second circumferential grooves. 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. The tread further includes a second circumferential row of blocks disposed between the second circumferential groove and a third circumferential groove. 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. The first common vertex is separated from the second circumferential groove by a circumferential tread rib.
