PNEUMATIC TIRE

A pneumatic tire includes: a tread portion; three or more main grooves provided on the tread portion at intervals in a tire width direction so as to extend in a tire circumferential direction; and a plurality of land portions partitioned between the main grooves adjacent to each other in the tire width direction, wherein the plurality of land portions include: ground contact areas having an arc shape in cross section in the tire width direction; and depressed portions opening to the ground contact areas, and the land portion having a larger ratio of opening surface area a of the depressed portions opening in the area between the main grooves adjacent to each other in the tire width direction with respect to surface area A of the area (a/A) has an arc-shaped ground contact area with a cross section in the tire width direction having a smaller radius of curvature.
