Abstract
A tire includes a tread provided with blocks formed among substantially longitudinal and transverse grooves, wherein among the blocks particularly broad intersections are formed, for example, by staggering substantially transverse grooves of circumferential rows axially in side-by-side relationship, of blocks with rounded corners, and wherein, inside such broad intersections, a stocky-shaped protrusion is arranged which has a lateral stiffness greater than the lateral stiffness of the surrounding blocks.
