摘要： 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.

摘要： A pneumatic tire has inner mediate land portions and center land portion(s) that are divided into a plurality of blocks by lateral grooves. Each of the lateral grooves includes a pair of wide portions opening to a main groove and a narrow portion coupling the pair of the wide portions. one-side-closed sipes are formed in a bottom of each of the lateral grooves formed in the inner mediate land portions. The one-side-closed sipes are open at the wide portions and close at the narrow portion. a both-sides-open sipe is formed in a bottom of each of the lateral grooves formed in the center land portion or portions. The both-sides-open sipe is open at the wide portions and at the narrow portion.
