Do Cars Have Inner Tubes?

[Faunus]

Cars do not use inner tubes but instead utilize tubeless tires. Principle of Tubeless Tires: Operating on the inflation expansion principle, tubeless tires rely on the outer tire's sealing gasket and the wheel rim's outer edge structure to contain the internal gas. The outer tire serves the dual purpose of an inner tube. The tubeless tire forms an integral seal with the wheel rim, demanding high manufacturing precision. Most employ die-cast aluminum one-piece wheel rims with superior tire positioning accuracy and minimal radial runout. Usage Precautions: Maintain specified air pressure at all times. While inner tube tires are made of high-quality rubber with excellent elasticity, flexibility, and wide pressure adaptability, tubeless tires offer wear resistance but poor pressure tolerance. Even tubeless tires must avoid puncture by sharp objects and contact with acids, alkalis, or oil contamination which accelerates rubber degradation.
