The pneumatic tire includes a tire tread portion in which a plurality of holes (46) for embedding stud pins (48) is provided, and a plurality of stud pins embedded in the holes. Each of the holes includes a hole body portion extending cylindrically in the depth direction of the holes. A narrow groove (52) extending in the depth direction of the holes is provided in the side wall of the hole body portion (46c). The pneumatic tire has a great resistance to pin drop while the performance of the tire on ice is at least maintained. |
