<p>A pneumatic tire has, on its tread (10), block rows (11, 12) partitioned by circumferential main grooves (14) extending in the circumferential direction of the tire and by lateral grooves (16) intersecting the circumferential main grooves. The blocks (11) in tread end regions each have two zigzag sipes (11a), and the blocks (12) in a tread center region each have one zigzag sipe (12a). The total length, the number of sipes, and a sipe rigidity index (F) of sipes that one block has on the tread surface are greater in the tread end region blocks (11) than in the tread center region blocks (12).</p> |
