Vacuum tires refer to tubeless inflatable tires, also known as "low-pressure tires" or "inflatable tires". In recent years, the use of vacuum tires on bicycles, motorcycles, cars, buses, and trucks has become increasingly widespread. Vacuum tires have high elasticity and wear resistance, as well as good adhesion and heat dissipation performance. Especially the all steel radial vacuum wheels, due to their economic durability, have been promoted to the logistics and transportation industry by the National Economic Commission and the National Tire Association.
Precautions for use:
1. It is necessary to maintain the prescribed air pressure
Tubeless tires are made of high-quality rubber, with good elasticity, strong flexibility, and a wide range of adaptability to air pressure. Even if the tire pressure is very high, it does not feel as hard as ordinary tires. Therefore, a pressure gauge should be used to check the air pressure. Unless the tire is punctured, tubeless tires generally do not deflate on their own. Therefore, when inflating, a pressure gauge should be used to check and maintain the specified pressure. It is not advisable to rely on the feel of the tire to determine whether to inflate it, as is the case with regular tires.
2. Not pressure resistant and not suitable for overloading. Vacuum tires are wear-resistant but not pressure resistant, especially considering the special situation of overloading in most trucks in China. If the overloading is too high, it is not suitable to use vacuum tires anymore. Some heavy-duty trucks will switch to vacuum tires for guidance, while the main driving wheels behind will still use ordinary steel wire tires. This ensures load-bearing capacity and improves driving comfort, and is also a good compromise method.
3. Tubeless tires should also avoid being punctured or punctured by sharp and hard objects during use, and avoid contact with acids and alkalis. Oil contamination can also accelerate rubber decomposition. The tires should be kept clean to prevent rubber aging and extend their service life.
4. Tubeless tires have good adaptability to asphalt and cement roads, and can maintain strong adhesion even if there is water on the road surface, with good stability. But for soil roads, especially muddy roads, the adhesion is small and the stability is poor. Motorcycles with tubeless tires are best used in urban areas and should not be driven on dirt roads in the suburbs.
5. Repair is more complicated and expensive. Once a vacuum tire is punctured and leaks air, it can be difficult to repair. The cost of repairing a vacuum tire once is much higher than that of a tire with inner tubes.
