PROBLEM TO BE SOLVED: To provide a pneumatic tire demonstrating the excellent durability by mitigating local stress concentration in a buttress part. SOLUTION: The pneumatic tire has a tread pattern including a plurality of slits 7 extending in the direction across the tire circumferential direction, and a plurality of shoulder blocks 8 divided by the slits 7. A block facing recess 11 which is located on the outer side in the tire width direction from an outer end 8a of the shoulder block 8, and has the length in the tire circumferential direction shorter than that of the outer end 8a of the shoulder block 8 is formed corresponding to each of the shoulder blocks 8. The block facing recesses 11 are arrayed with a spacing along the tire circumferential direction in a range of the height of 10-40% of the tire sectional height H with the outermost diameter position PP of the tread surface 6.
