Today, vacuum tyres have become the standard for heavy trucks and are increasingly favored by drivers because of their own advantages. It not only has high elasticity and wear resistance, but also has good adhesion and heat dissipation properties. Compared with conventional tires, the safety of driving is greatly improved.

Although truck vacuum tyres have many advantages, anything is coexisting with "pros and cons" and the same applies to vacuum tyres. Let's talk about the "pros and cons" of vacuum tyres.

The advantages of vacuum tyres:

1, strong elasticity, puncture resistance. As the surface of the vacuum tire is a layer of high-quality rubber, the external surface tension increases after inflation, so a certain pressure is formed on the inner surface, thereby improving the self-sealing ability of the break. Even if the tire is punctured, the gas will not be completely discharged in an instant like an ordinary tire, but will continue for a certain period of time, ensuring the safety during high-speed driving.

2, wear, strong heat dissipation. Although vacuum tire wheels have a larger diameter than ordinary rims, they are not affected by the heat of the brake drum during driving. Because there is no inner tube and lining, the tire and the wheel ring are sealed together. The high temperature generated by friction between the tire and the road surface during high-speed driving of the vehicle is directly dissipated inside the steel (hot air) through the steel ring. Not only can quickly reduce the temperature of the tire, but also can extend the life of the tire.

3, good adhesion. Because the vacuum tire is a flat tire in the metric unit 315/80R22.5, 295/80R22.5,275/70R22.5, the tire crown angle is zero, so the adhesion is strong. Not only can we maintain better driving stability and less friction, but it also helps to reduce vibration and increase vehicle speed.

Disadvantages of vacuum tyres: Vacuum tyres are wear-resistant but not pressure-resistant. In most cases, trucks in our country are overloaded, so they have certain limitations. Another point is that vacuum tire repair is not only troublesome and the cost is relatively high. In some areas, there are even few manufacturers for repair, which is more troublesome for users.

Although vacuum tires have many advantages, their shortcomings cannot be ignored. Users can choose the right tire according to their own situation and local development, otherwise there is no place to repair it is a big loss.
