Let's talk about the advantages and disadvantages of vacuum tires
Disadvantages of vacuum tyres:Vacuum tire wear resistance, but not pressure, especially for the majority of China's Heavy Truck Overload exists in this special situation, too much overloading is not suitable for the use of vacuum tires. Some heavy-duty trucks will guide the rotation into the vacuum tire, behind the main driving wheel bearing still use ordinary steel wire tire, which guarantees the carrying capacity, and improve the driving comfort, but also can be regarded as a good way to compromise.Repair more trouble, the high cost of vacuum tire punctured once it patched up more trouble, a vacuum tire repair cost is tubeless tire are also much higher. Guangdong, Fujian area of the garage is more, so the use of vacuum tire is widely used, but other local repair shop is not many, many drivers worry no place to tire repair, so the other region is relatively less used.
Low fuel consumption = earn money - vacuum tires are flat tires in metric units 315/80R22.5295/80R22.5275/70R22.5, and the tread angles are zero, so adhesion is strong. The utility model can keep good driving stability and little friction, and is beneficial to shock absorption and speed increase. The alignment of the belt is high, the radial runout of the wheel is small, and the resistance is small. Thus save fuel 3%.
Super wear = save money - vacuum tires are much larger than conventional rims and are not affected by brake drum heat during driving. No inner tubes and lined with tire and car rim seal as one of the vehicles at high speeds, the heat generated by the tire and road surface friction, the internal (hot air) by direct cooling coils quickly reduce the tire temperature, thereby prolonging the service life of the tire.
Advantages of vacuum tires:Puncture resistance = safe vacuum tire surface is a layer of high-quality rubber, inflated surface tension increases, the inner surface of a certain pressure, improve the ability of self to break, once broken, unlike ordinary tire as gas in an instant all discharge end, will persist for some time, ensure the safety of high-speed driving.
