![]() Once the pneumatic tire is punctured and leaking, it is more troublesome to repair, and the cost of repairing a vacuum tire is much higher than that of an inner tube tire. The pneumatic tire has no inner tube and cushion belt, which effectively reduces the heat generated by friction between the inner tube and the inner cavity of the tire, and the air inside is in direct contact with the rim, and the heat can be directly distributed through the rim, so that the tire temperature will not be too high and prolong the service life of the tire. ![]() ![]() Pneumatic tires are wear-resistant, and have better dynamic balance performance, so that driving comfort can be improved, so it is more suitable for long-distance high-speed long-distance driving. People usually call tubeless tires, is the tire without an inner tube, this tire wall attached to a layer of rubber sealing layer of about 2mm to 3mm thick, in the sealing layer underneath a layer of self-adhesive layer made of a special mixture of unvulcanized rubber, the use of the tire wall and the rim of the airtight layer to ensure that the tire and The airtight layer of the inner wall and bead ensures a good airtightness between the tire and the rim, thus replacing the role of the traditional inner tube, the outer tire also plays the role of the inner tube, while the tire is inflated, the toe port is closely combined with the rim, effectively avoiding air leakage.
