A first inner widthwise groove (16i) which opens to a circumferential groove (14a), and a first outer widthwise groove (16e) which extends outward in the tire widthwise direction and opens to the circumferential groove (14a) at a location facing the first inner widthwise groove (16i) are arranged in the tire circumferential direction on at least one side of the tire equator line of the tread portion (10). The first inner widthwise groove (16i) has an inflection point (CP) where a direction of a convex or a concave with respect to the tire circumferential direction changes, and has a curved convex shape toward a tire normal rotation direction side from the inflection point (CP) to the circumferential groove. A groove wall (16e1) forming the first outer widthwise groove (16e) on a side opposite to a tire normal rotation direction (R) extends outward in the tire widthwise direction while being inclined toward a side opposite to the tire normal rotation direction (R).
