Abstract
A pneumatic tire includes two circumferential main grooves within a ground-contact width of a tread, and a group of polygonal blocks between the two circumferential main grooves. The group of polygonal blocks includes a plurality of polygonal blocks arranged in at least two longitudinal rows in a tire circumferential direction and a plurality of transverse rows in a tire width direction. Each polygonal block has not less than five sides, and is defined by narrow grooves. The polygonal blocks in the adjacent longitudinal rows are arranged so as to be staggered from each other in the tire circumferential direction. The group of polygonal blocks has a widthwise center that is positioned within a 50% width region of the ground-contact width of the tread across a tire equatorial plane.
