PROBLEM TO BE SOLVED: To provide a pneumatic tire increased in wear resistance while maintaining high drainage property. SOLUTION: This pneumatic tire has, in a tread part 2, a plurality of main grooves 22 extending in the circumferential direction of the tire. The pneumatic tire satisfies the requirement 0.3(TW/2)≤L0≤0.6(TW/2) when a tire ground-contact width is TW and the length of the tire in the tire width direction from the side wall 22ba of the second main groove 22b on the outer side of the tire in the tire width direction to the equator C of the tire on the outermost side of the tire in the tire width direction is L0. When the center area Lc of the tire in the tire width direction from the equator C of the tire to the outer side of the tire in the tire width direction is set within the range of 0.33(TW/2)≤Lc≤0.63(TW/2), the tire is assembled in a normal rim, and the tire is filled with a pressure which is 5% of a specified internal pressure, the tread surface 21 of the center area Lc of the tire in the tire width direction has a recess 28 recessed radially inward of the tire from the outer area Ls of the tire in the tire width direction further on the outside of the tire in the tire width direction than the center area Lc of the tire in the tire width direction.
