[Previous technology] As described in Japanese Patent Application Laid-Open No. 8-3 2 3 8 7 5, a tire repair chamber separated by at least one inner ring is formed on the inner side of the tread of the tire body, and it is sealed by reuse. The tire puncture sealant in the tire puncture sealant chamber which seals the tread surface caused by nail repair, etc., is used to slow down the outflow of air from the tire puncture repair tire. The above conventional tires with a puncture-reducing agent are coated with talc on one of the two contact surfaces or a part of the contact surface between the inner rings when the inner ring is combined with the tire body before vulcanization. Vulcanization molding is performed in the state of the release agent, so that the tire body and the inner ring are combined into one body, so that the part to which the release agent is applied is left in a non-adhesive state to form a tire repair agent chamber. [Problems to be Solved by the Invention] However, if a rubber tire raw material composed of a tire body and an inner ring 2 is inserted into a heating mold for vulcanization and molding, the inner ring will be stretched, and the release agent will be poor. The density of talc produces high and low parts, which makes it impossible to clearly distinguish the adhesive sulfurized part and the non-adhesive sulfurized part, which may make it impossible to form a correct tire puncture chamber. Therefore, it is difficult to shape the paper scale. Applicable to China National Standard (CNS) A4 specification (210 X 297 mm) --------------.
