Why do some electric car manufacturers like to use vacuum tubes?

The reason for this depends on the fact that the tubeless has good performance.

This is because the tubeless can be scrapped very quickly, and then the buyer can go to the electric vehicle company for repair.

I think the reason for this may be that vacuum tires have a little more withstand capacity.

I think this is because vacuum tires will be more comfortable to use, so many people use them.

Three major benefits: 1. Puncture resistance and safety - vacuum tires.

The surface is a layer of high-quality rubber, the surface tension increases after inflation, forming a certain pressure on the inner surface, improving the self-sealing ability of the break, once punctured, unlike ordinary tires, the gas is all discharged in an instant, it will last for a certain time, ensuring the safety of high-speed driving.

Second, super wear-resistant and save money - vacuum tire rims.

It has a larger diameter than a normal rim and is not affected by the heat of the brake drum while driving. Since there is no inner tube and lining, the tire and the wheel rim are sealed as a whole, and when the vehicle is driving at high speed, the high temperature generated by the friction between the tire and the road surface can quickly reduce the tire temperature through the direct heat dissipation of the steel rim inside (hot air), thereby prolonging the service life of the tire.

3. Low fuel consumption and making money - vacuum tires are flat tires in the metric unit 315 80r 80r, and the tire crown angle is zero, so the adhesion is strong. It can maintain good driving stability and less friction, which is conducive to shock absorption and increase vehicle speed. The positioning of the belt layer is high, the radial runout of the wheel is small, and the resistance is small.

Thus saving fuel3.

High safety: Since the tubeless is made of high-quality rubber, the surface tension is high after inflation, and at the same time, a certain pressure will be formed on the inner surface. When the tire is accidentally punctured, it has a certain self-sealing ability, and the gas will not leak instantaneously like ordinary tires.

This increases the vehicle's driving safety.

Low energy consumption: the tubeless has good driving stability, and at the same time, the positioning of the internal belt layer is also high, the radial runout of the tire is small, and the rolling resistance is also small. This will have the effect of saving electricity.

Good heat dissipation and long life: due to the lack of inner tube, the tire not only reduces the friction between the inner tube and the inner surface of the tire during high-speed operation, but also the high temperature generated by the tire and the road surface will be directly dissipated through the steel rim with the tire and the air inside the tire, so as to reduce the tire temperature faster and prolong the service life of the tire.

Precautions: Tubeless tires are made of high-quality rubber, with good elasticity and strong flexibility, and a wide range of adaptability to air pressure.

In addition to punctured tires, tubeless tires generally do not deflate on their own, so when inflating, it is necessary to check with an air pressure gauge and maintain the specified pressure, and do not decide whether to replenish the air by feeling like ordinary tires.

Friend, I suggest you buy ordinary internal and external tires, although it doesn't look as good as the vacuum, but you can't be wrong with listening to me, I'm a car repairer, I have encountered a, a vacuum tire electric car, the tire is too troublesome, repair the car tire is not to be repaired, because it is too troublesome to disassemble and assemble, not like a car. I feel that the installation of car tires for electric vehicles is a selling point of manufacturers, but it is not actually applicable.

Compared with the vacuum tire and the gall tire, it can be said that each has its own good, vacuum tire, this tire rubber density is good, in the road a puncture, you can also ride a few kilometers to several 10 kilometers, when repairing the tire can generally be used fire or rubber strip to make up two kinds, the cost of fire repair is higher at about 10 yuan, the rubber strip is 3-5 yuan, when the rubber strip is repaired after a period of use, it will leak again, and then leak when it is not good to make up, so its maintenance cost is too large, the only benefit is that you will never be bad on the way because the tire can not come back.

Vacuum tires are tubeless pneumatic tires, also known as "low-pressure tires" and "pneumatic tires", vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance, especially all-steel radial vacuum wheels, economical and durable.

Vacuum tires are widely used in bicycles, motorcycles, cars, buses, and trucks in recent years. It is promoted by the National Economic Commission and the National Tire Association to the logistics and transportation industry.

Most of the electric vehicles have been replaced with tubeless, in addition to saving costs for manufacturers, what are the benefits?

Tubeless or tubeless: There is no accepted definition, and the following are the advantages of tubeless and inner tubes:

Tubeless tubeless is tubeless, but it can be retrofitted. Some of those with inner tubes can be modified into tubeless, and most of them cannot be modified with tubeless.

Tubeless is generally wide carrying capacity, the stability is slightly better than that of the inner tube (the tire with the inner tube is generally narrow and the safety performance is relatively weak), the vacuum tire is about 2 times more expensive than the inner tube, and the inner tube is cheap and affordable.

A variety of options for tubeless repair:

Remove the tire and repair it like an inner tube inside the tire.

Remove the valve core of the tire, inject a bottle of self-rehydrating fluid, and pump the valve center on the upper return.

Use foamed water to find the air leak and repair the tire with a vacuum patch.

The inner tube can only be disassembled and repaired.
