Abstract
A vehicle wheel tyre includes a carcass structure, a belt structure, and a tread. The tread includes four circumferential grooves and a plurality of transverse grooves that define at least five circumferential rows of blocks, each block approximating a polygon. The longitudinal sides of the blocks are inclined in the same direction at a predetermined angle to the equatorial plane of the tyre. The blocks of each row are circumferentially staggered relative to the blocks of the next row. The blocks of the central row include stiffening means. Profiles of the front sides of the blocks of the central row are the same as the profiles of the rear of the blocks of the central row rotated through 180°. The blocks of the shoulder rows are elastically linked to the blocks of the intermediate rows.
