发明名称 TREAD PATTERN FOR CAR TIRE
摘要 A tire tread includes a 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 common vertex spaced from the second circumferential groove. The common vertex is separated from the second circumferential groove by a continuous circumferential tread rib. 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. The solid tread portion extends from the first circumferential groove to the continuous circumferential tread rib, and 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.
