A pneumatic tire includes a plurality of stud pins inserted into a plurality of holes (20A) disposed in the tire surface. The stud pins each include a body portion and a flange disposed closer to the bottom side of each of the holes (20A) than the body portion and having an outer diameter larger than the body portion. The holes (20A) each include a securing portion (22) coming into contact with the outer peripheral surface of the body portion of the stud pin to secure the stud pin and an enlarged diameter portion (23) disposed closer to the bottom wall side of the hole (20A) than the securing portion (22), having an inner diameter larger than the securing portion (22), and coming into contact with the outer peripheral surface of the flange of the stud pin to secure the stud pin. The side wall of the enlarged diameter portion (23) is provided with a protrusion (30A) protruding toward the interior of the hole (20A). The protrusion (30A) deforms to match the outer peripheral surface of the flange inserted into the enlarged diameter portion (23), such that the entire surface of the protrusion comes into contact with the outer peripheral surface of the flange. |
