What is a vacuum tire? What's the difference with ordinary tires?

The scientific name of vacuum tire is tubeless tire, which has good shock absorption and grip, low cost, and can persist in driving for a period of time due to minor damage, but its durability is poor. Ordinary tires, which are mostly used in bicycles and large cars at present, have strong durability and load-bearing, but the disadvantage is that once they are slightly damaged, they will leak air immediately.

The scientific name of vacuum tire is tubeless tire, which was originally named to distinguish it from ordinary tubeless tire. Compared with the tubed tire, tubeless tire has the advantages of higher safety and durability, higher manufacturing cost, faster heat dissipation speed and lower fuel consumption, and is rapidly replacing the traditional tubed tire.

The vacuum tire will not burst at high speed, and it will not leak light quickly after being nailed, so it is convenient to repair the tire. The disadvantage is that driving on signposts is slippery than ordinary tires. The way to distinguish vacuum tires from ordinary tires is to move the "valve" by hand. Ordinary tires are fixed, and vacuum tires have some room for movement.

Due to the reduction of inner tube and cushion belt, the weight of tire is reduced, and the spare parts of rim are also reduced through locking ring, further reducing the weight. Replacing the whole set of tires with vacuum tires can reduce hundreds of kilograms. Vacuum tires have low driving resistance and can save fuel by 3%. The reduction of driving self-respect and fuel consumption is an extra profit for truck drivers.
