摘要 |
A pneumatic tire has a rib sectionalized by main grooves extending along a tire circumferential direction in a center portion of a tread surface. Depressions are arranged in series in a center portion in a width direction of the rib so as to leave a space in the tire circumferential direction. The depressions extend in the tire circumferential direction and become wider from both end portions in a longitudinal direction toward a center portion.
