A tyre for a motor car includes a tread and two shoulders. The tread includes at least one 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 converge at a common vertex spaced from the second circumferential groove. The common vertex is separated from the second circumferential groove by a continuous circumferential tread rib. A second transverse groove that delimits a first block is separated from a first transverse groove that delimits a circumferentially adjacent block by a solid tread portion. The solid tread portion extends from the first circumferential groove to the circumferential tread rib and forms a single body with the circumferential tread rib, spacing the first block and the circumferentially adjacent block from each other.
