It is estimated that the contact point between the wheel frame and the tubeless tire is not smooth enough, and it is not easy to leak when stationary. When moving, the contact point between the wheel frame and the tubeless tire will move slightly, and it is easy to leak air.

1. Introduction:

Vacuum tires are tubeless pneumatic tires, also known as "low-pressure tires" and "pneumatic tires". Vacuum tires are It has high elasticity and wear resistance, and has good adhesion and heat dissipation performance. Especially the all-steel radial vacuum wheel is economical and durable.

Vacuum tires have been increasingly used on bicycles, motorcycles, cars, buses, and trucks in recent years. Promoted to the logistics and transportation industry by the National Economic Council and the National Tire Association.

2. Advantages

Compared with general inner tube tires, all-steel radial vacuum tires have the following three major advantages

One: puncture resistance = safety-- The surface of a vacuum tire is a layer of high-quality rubber. After inflating, the outer surface tension increases, forming a certain pressure on the inner surface, which improves the self-sealing ability of the breach. Once punctured, unlike ordinary tires, all the gas will be released in an instant. Lasts for a certain period of time, ensuring safety when driving at high speed.

Second: Super wear-resistant = save money - the diameter of vacuum tire rims is larger than that of ordinary rims, and they will not be affected by the heat of the brake drum during driving. Since there are no inner tubes and linings, the tire and the wheel rim are sealed as one. When the vehicle is driving at high speed, the high temperature generated by the friction between the tire and the road surface is directly dissipated internally (hot air) through the steel rim to quickly reduce the tire temperature, thus extending the tire life. service life.
