A heavy load tire includes a first inner widthwise groove which opens to a circumferential groove, and a first outer widthwise groove which extends outward in the tire-widthwise direction and opens to the circumferential groove at a location facing the first inner widthwise groove are arranged in the tire-circumferential direction on at least one side of the tire equator line of the tread portion. The first inner widthwise groove has an inflection point 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 to the circumferential groove. A groove wall forming the first outer widthwise groove on a side opposite to a tire normal rotation direction extends outward in the tire-widthwise direction while being inclined toward a side opposite to the tire normal rotation direction.
