| 摘要 | A pneumatic tire has a tread pattern including a lateral groove extending in a direction intersecting a tire circumferential direction and a shoulder block comparted by the lateral groove. A depression region in which a plurality of depressions extending in the tire circumferential direction are arranged in a tire width direction are formed on a surface of the shoulder block in an outer side in the tire width direction than a ground-contact end. The depressions are open to the lateral groove, and are segmented in a center portion in the tire circumferential direction of the shoulder block. | ||
