Abstract: A pneumatic tire in the present invention has a narrow groove extending in the tire circumferential direction on a portion closer to a tire equator than a ground contact end, and dividing a shoulder land into a main land close to the tire equator and a sub land close to the ground contact end. An outer sidewall of the narrow groove has: a straight line extending inward in a tire radial direction from an outer circumferential surface of the sub land; a first circular arc smoothly connected to the straight line; and a second circular arc smoothly connected to a groove bottom of the narrow groove. The first circular arc has a center of a circular arc closer to the equator than the outer sidewall. The second circular arc has a center of a circular arc closer to an outside in a tire width direction than the outer sidewall.
