PROBLEM TO BE SOLVED: To provide a pneumatic tire with an enhanced heat radiation effect at a tread part while maintaining rigidity at a land part.SOLUTION: A sipe 10 is formed on a tread surface 1, the sipe 10 extending obliquely with respect to a peripheral direction of a tire, the width W1 of the sipe 10 being smaller than the depth D1 of the sipe 10. At least one end of the sipe 10 is terminated in the land part. An air inflow part 11 opened on the tread surface is formed at least on one side of sipe walls 10c facing the sipe 10's peripheral direction of the tire. A maximum depth D1 of the sipe 10 and a maximum depth D2 of the air inflow part 11 satisfy an expression 1≤D1/D2≤15. |
