ことを目的としている。In the case of replacing a general running tire with a snow tire or a studless tire with a conventional integrated tire, the tire and the tire wheel are generally replaced integrally, so that the replacement operation is easy. However, since a replacement tire having a tire wheel mounted on a tire is heavy and bulky, there is a problem in handling such as transportation and storage. In addition, even if only the tread portion is worn, the performance of the tire is greatly reduced, so it is necessary to replace the entire tire, and there is a problem in resource utilization efficiency. In order to solve the above-described problems, the present invention makes it possible to replace a tread portion of a tire, easily replace a tread portion with a tread shape adapted to a road condition, and transport and store the tread portion. It is an object of the present invention to provide a tread replaceable tire that is easy to handle and that can also sufficiently recover a predetermined performance of the tire by replacing the tread portion even with respect to wear of the tread portion. .

Each of 212104 is a method of fixing using a frictional force between the tread ring and the tire main body generated by the air pressure of the tire main body, and reinforcing the breaking force generated in the tread ring during use by a tire cord arrangement method. is there. However, when the circumferential force is repeatedly applied to the tread ring for a long period of time, there is a high possibility that the position of the tread ring is shifted rearward of rotation with respect to the tire main body. The displacement is more likely to occur closer to the edge of the tread ring, and as a result, the stress due to the deformation of the edge of the tread ring is maximized, and the edge of the tread ring is likely to break. Such a phenomenon can be explained mechanically. In order to solve the problems described above, the present invention provides a corresponding projection and recess on the fitting surface of the tire main body and the tread ring, eliminates displacement of the tread ring with respect to the tire main body, prevents deformation, and The purpose of the present invention is to provide a tread replaceable tire that does not cause ring breakage.

A projection or depression (4) corresponding to the depression or projection (3) of the tire main body is provided on the entire inner peripheral surface of the ring (2), and the tire main body and the tread ring are shown in FIG.
Combine with the state. The attachment and detachment of the tread ring (2) to and from the tire body (1) is performed by increasing and decreasing the air pressure inside the tire body (1) to increase and decrease the outer diameter of the tire body (1). Due to the arrangement of the tire cords, the tire body (1) has a structure in which expansion and contraction in the circumferential direction is apt to occur on the outer periphery of the tire body with respect to increase and decrease in the internal air pressure, and expansion and contraction in the width direction perpendicular to the circumference hardly occurs. It has. The tread ring has a structure for preventing expansion and contraction in the circumferential direction and in the width direction perpendicular to the circumference by the arrangement of the tire cords. By the above means, the stress generated in the tread ring during use can be dispersed and reduced throughout the tread ring. Furthermore, the fitting combination of the tread ring and the tire main body can be kept in a good state.
