Abstract: There is provided a technology for minimizing shape deformation of a block formed on a tire in a case of braking, driving, or the like of the tire. There is provided a tire with an interlocking band type 3D kerf according to the embodiment of the invention, including a kerf having a road holding part which is a space formed in the block by extending in a direction inward to the tire from a ground contact surface of the block that comes into contact with a road, a projection part which is a space in the block with both side wall surfaces that is formed by extending from the road holding part and at which a protrusion portion having a shape projecting from one side wall surface is formed, and a base part which is a space in the block that is formed by extending from the projection part.

Abstract: An embodiment of the present invention provides a technique for minimizing the deformation of the shape of a kerf by improving the durability of a blade used in forming the kerf during tire vulcanization. A 3D kerf-forming blade according to an embodiment of the present invention is installed in a tire vulcanization mold for forming a kerf and includes a frame formed in a shape of a plate having a wave shape in a cross section horizontal to a thickness direction and a support formed in a shape of a bar having one side connected to the frame and the other side connected to another frame.
