PROBLEM TO BE SOLVED: To suppress both uneven wears of toe-and-heel wear and early uneven wear of a block edge. SOLUTION: This pneumatic tire has main grooves 2 carved in a tire tread 1 continuously in the tire circumferential direction and lateral grooves 4 connecting the main grooves 2 to each other or the main groove 2 to a tire grounding end 3, the main grooves 2 and the lateral grooves 4 forming a block 5. The side wall 6 of the block 5 has a recessed part 7 having an opening part 8, the opening part 8 being located closer to the groove bottom side than 3/4 of the block-side wall height from the groove bottom of the groove adjacent to the side wall 6. The sectional area vertical to the side wall 6 of the recessed part 7 is reduced from the adjacent groove-directional center part of the side wall 6 to both the adjacent groove-directional ends of the side wall 6.
