Vacuum tire is a kind of tubeless pneumatic tire, also known as "low pressure tire" and "pneumatic tire". In recent years, vacuum tires are widely used in bicycles, motorcycles, cars, buses and trucks. Vacuum tires have high elasticity and wear resistance, as well as good adhesion and heat dissipation.
superiority
1. Puncture resistance
The surface of vacuum tire is a layer of high quality rubber. After inflation, the external tension increases, forming a certain pressure on the internal surface, and improving the self-sealing ability of the breach. Once a tire bursts, unlike ordinary tires, the gas is not completely exhausted in an instant, but lasts for a certain period of time to ensure the safety when driving at high speed.
2. Super wear resistance
The diameter of vacuum tire rim is larger than that of ordinary rim, and it will not be affected by the heating of brake drum when driving. Because there is no inner tube and lining, the tire and rim are sealed into a whole. When the vehicle runs at high speed, the high temperature generated by the friction between the tire and the road surface will be directly radiated by the steel ring (hot air) inside, which will quickly reduce the tire temperature, thus prolonging the service life of the tire.
3. Low fuel consumption
Vacuum tires are flat tires with metric units of 3 15/80R22.5, 295/80R22.5 and 275/70R22.5. The crown angle of the tires is zero and the adhesion is strong. It can maintain good driving stability and low friction, which is beneficial to shock absorption and speed improvement. High belt positioning, small wheel radial runout and small resistance. Thus saving 3% fuel.
Trucks and trucks using tubeless tires have higher wear resistance, safety, comfort and stability than ordinary tires.
