Which is better, vacuum tires or ordinary tires for electric vehicles? What are the advantages and disadvantages of these two kinds of tires?

First of all, let's learn about the vacuum tires of electric vehicles. It has no combination of inner and outer tires, and the surface 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 punctured, it will last for a certain time, unlike ordinary tires, which will ensure the safety at high speed.

In addition, compared with ordinary tires, vacuum tires have better wear resistance and longer service life. Of course, the heat dissipation performance of the vacuum tire will be better, because the vacuum tire has no inner tube and lining. When the electric vehicle is driving at high speed, the high temperature generated by friction will directly dissipate heat through the steel ring, which makes it easier to dissipate heat.

However, compared with ordinary tires, vacuum tires are more expensive, basically many times the price of ordinary tires, and the maintenance costs will be higher.

Let's look at the ordinary tire again, because it is a combination of inner and outer tires and wheels. This kind of tire has obvious advantages, relatively cheap price, convenient maintenance and relatively low maintenance price.

However, compared with vacuum tires, ordinary tires have poor stability and wear resistance, and are more likely to be punctured. Once punctured, the electric car is quite laborious to implement and is easy to be scrapped.

Therefore, regardless of the price, vacuum tires will be relatively better.
