PROBLEM TO BE SOLVED: To provide a tire capable of further suppressing the generation of partial wear while suppressing the generation of stone biting. SOLUTION: In the tire, a recessed hole 10 is formed inside a tire radial direction from a surface of a tread contacting with a road surface. The hole 10 is formed of an outer hole 20 extending along the tire radial direction D from the surface of the tread and formed circularly in its cross section along the tread width direction W and the tire circumferential direction R, and an inner hole 30 continuing to the outer hole 20 and positioned inside the tire radial direction relative to the outer hole 20. The inner hole 30 is formed of a column surface 32 extending along the tire radial direction D, a bottom surface 34 becoming the bottom of the inner hole 30, and a protruded part 36 continuing to a part of the column surface 32 and protruding to the inside of the inner hole 30.
