Why doesn't the tire leak when punctured?

[EvanLee]

The reason why a punctured tire doesn't leak air: Most cars are equipped with tubeless tires, which have an additional rubber sealing layer about 2-3 mm thick on the inner wall of the tire, providing a certain level of protection. Here are precautions for using tubeless tires: 1. Check tire pressure with a pressure gauge: Tubeless tires must maintain the specified air pressure. Made of high-quality rubber, they have good elasticity and flexibility, with a wide range of adaptability to air pressure. Even at high pressure, they don't feel as hard as ordinary tires, so tire pressure should be checked with a pressure gauge. 2. Road condition requirements: Tubeless tires perform well on asphalt and concrete roads, maintaining strong traction and good stability even on wet surfaces. However, they have poor traction and stability on dirt roads, especially muddy ones. Motorcycles with tubeless tires are best used in urban areas and are not suitable for driving on rural dirt roads.
