A heavy duty tire 10 includes a recess portion 34, a circumference-direction air entry and exit promotion portion 36 and an air-catching wall portion 42. The recess portion 34 is formed in a buttress portion 26 and opens to a tire outer side. The circumference-direction air entry and exit promotion portion 36 is disposed at one side of a floor portion 40 in a tire rotation direction and includes a slope 46 that, from the floor portion 40 toward a tire surface, gradually decreases in depth from the tire surface. The circumference-direction air entry and exit promotion portion 36 facilitates access of air toward the floor portion. The air-catching wall portion 42 is disposed at the opposite side of the floor portion 40 from the circumference-direction air entry and exit promotion portion 36. The air-catching wall portion 42 has a greater angle relative to the tire surface than the slope.
