摘要： A tire having stud holes (stud recesses) for stud insertion featuring both good demolding performance at curing and good anti-stud-loss performance in use is provided. The tire has the stud holes 3 on the surface 14a side of the tread 14. The stud holes 3 each have an opening side part 31 on one side along the central axis 3C thereof, which opens on the surface 14a of the tread 14, and a bottom side part 32 on the other side along the central axis 3C thereof. The inner peripheral surface 36 of the bottom side part 32 is formed in a curved surface swelling outward away from the central axis 3C of the stud hole 3. And the maximum diameter C position 36M of the inner peripheral surface 36 of the bottom side part 32 is located on the hole bottom surface 35 side of the intermediate position between the boundary position of the opening side part 31 and the bottom side part 32 and the hole bottom surface 35.

摘要： A stud and a tire fitted with the studs featuring improved ice braking performance and anti-stud-loss performance are provided. To that end, the stud (1) according to the present invention, which is to be fitted in a stud recess formed on the tread surface side of the tire, includes a columnar body section (2), a pin section (3) disposed on one end in the direction along the central axis of the body section, and a flange section (4) disposed on the other end in the direction along the central axis of the body section. The body section, the pin section, and the flange section are respectively so formed as to have a length direction and a width direction orthogonal to the central axis 1C. And the length direction of the pin section (3) and the length direction of the flange section (4) face in the same direction, whereas the length direction of the pin section (3) and the flange section (4) faces in a different direction from the length direction of the body section (2).
