PROBLEM TO BE SOLVED: To provide a pneumatic tire with reduced tire weight, while ensuring resistance against external damage of a side wall part. SOLUTION: The pneumatic tire 1 has a tread part made of tread rubber 5 and a side wall part made of a side wall rubber 6. When a stipulated value K=Sc/St/(100-α) is defined, the stipulated value K is within a range from 0.13 or more to 0.15 or less. Where, a cross-sectional ratio of the tread rubber 5 to the side wall rubber 6 in a cross-sectional view in a tire meridian direction is (Sc/St), and an aspect ratio of the tire isα[%].
