Provided is a pneumatic tire having a tread surface (1) with a tread pattern having: at least two circumferential grooves (2) extending in the tire circumferential direction to define land sections (3) on the outer sides in the tire width direction; and lateral grooves (4) extending in the tire width direction to partition the land sections (3) into a large number of blocks (5). In addition, in each of the blocks (5), a cutout (6) is formed in the center region of an edge portion of the block (5), the edge facing the corresponding circumferential groove (2). The cutout (6) has plural steps in the tire width direction. This structure improves the performance of running on a muddy ground with the resistance to uneven wear and the driving stability on general road surfaces maintained respectively at sufficient levels. |
