Abstract:
Provided is a pneumatic tire having a tread surface in which two circumferential direction main grooves continuous in a tire circumferential direction are arranged on left and right sides of a tire center, and land portions are defined by the circumferential direction main grooves as ribs or blocks having lug grooves. Multiple fine grooves are provided in each of right and left walls of the circumferential direction main groove, the fine grooves being inclined to the tire circumferential direction and provided in regions along the circumferential direction main groove, covering at least 50% of the entire circumference thereof in total. In each of the two circumferential direction main grooves on corresponding tire shoulder sides, the fine grooves in the right and left walls are inclined to the tire circumferential direction in the same direction in a plan view in a tire radial direction. In each of the two circumferential direction main grooves on a tire center side, the fine grooves in the right wall and those in the left wall are inclined to the tire circumferential direction in directions opposite to each other in a plan view in the tire radial direction.
