No-puncture tire and no-puncture tire manufacturing method

摘要

PROBLEM TO BE SOLVED: To remove air from tires of automobiles, motorcycles, bicycles, electrically assisted bicycles, wheelchairs, rear cars, etc. for several months. In addition, when traveling on a rough road, the vehicle punctures while traveling. There is a need for a low-cost tire that does not require air replenishment and does not puncture. SOLUTION: An annular space (10) formed by a tire outer skin (11) and a rim (12) is provided with a thermosetting elastomer sponge tube (FE) shaped along the inner surface of the annular space (10). No puncture tire (20). An annular heat-foaming thermosetting elastomer tube (PE) is inserted into the annular space (10) of the tire outer skin (11) and the rim (12), and is heated and foam-cured together with the tire outer skin (11) and the rim (12). It manufactures by forming the thermosetting elastomer sponge tube (FE) of the shape along the space inner surface of the annular space (10) in the annular space (10). [Selection] Figure 1
