2 Poor. 3 General.

4 good **high rate, **good performance.

Weather resistance. 1. Generally, it is easy to burst at high temperatures, and when it is low temperature, the air pressure is easy to be insufficient.

2 Generally, in the case of low temperatures, the tires become stiffer, not to mention elasticity.

3.Poor: When the temperature is high, the tire becomes softer, the support force and elasticity decrease, and it is easy to get out of the tire; Tires harden at low temperatures.

3 Larger should only be used for low-speed vehicles.

4 Small can be used on both medium and low speed vehicles.

**。1 medium.

2 Low. 3 High.

4 in.

Solid tires, honeycomb tires, hollow tires, vacuum tires, choose a good tire.

Non-pneumatic tires do not need to be inflated, relying on the material and structure of the tire itself to bear weight and bear a certain amount of cushioning.

Pneumatic tires for electric vehicles.

1. No need to inflate, no need to replenish air every once in a while like pneumatic tires, maintenance-free, more convenient to use;

2. Without inflation, there will be no puncture, which eliminates the potential safety hazards caused by punctures during riding;

3. Sunscreen does not puncture tires. Ordinary tires are overinflated, and in hot weather, there will be a puncture;

4. Good wear resistance, not afraid of nails;

5. Comfort: For solid tires, the cushioning will be slightly worse than that of pneumatic tires; For tires with shock-absorbing structures, there is a certain cushioning performance, and comfort is also okay.

Pneumatic tires are not required.

The main thing is not afraid of a puncture, not afraid of puncture, especially now that the lead-acid battery is getting heavier and heavier, the 60v 72v battery tire puncture is basically impossible to push by manpower, and if you push it hard, the inner tube will also be a mess by nails and the like It is completely invalid, and you can't repair the tire if you can't push it, and it is a lot of money to call the car in the past, so from this point of view, there is still a merit in not inflating solid tires.

ps: There is a bit of a misunderstanding about the solid tire on the net, saying that the solid tire is hard, that must not be electricity, the driving distance is long and fast, the soft tire is power-hungry The driving speed is slow, part of the energy is used to deform the tire to consume, the hard tire is the energy conversion as much as possible, of course, the disadvantage is that the suspension feeling is a little poor... This one has hollow solid tires anyway and individuals can choose at will...

I feel that solid tires are an inevitable trend, and the way of outer tire + inner tube is too old-fashioned, and there is no economic advantage.

Hope mine can help you.

Not good. Non-pneumatic tires are not elastic and smooth on the road without pneumatic tires. That's why vehicles are equipped with tires.

Some people say that trains don't have tires because they run on smooth steel rails, but roads are not as smooth as tracks. Therefore, it is better to install pneumatic tires for all vehicles driving on the road.

There are benefits to pneumatic tires for electric vehicles, but there are also disadvantages. The advantage is that it does not need to be inflated, so you can ride with confidence. The disadvantage is that the electric car will feel hard and not so comfortable to ride.

It is more wear-resistant, has a long service life, and will not puncture tires, but it is noisy, comfortable, and not too fast.

Summary. Hello! Friend.

Each has its own advantages and disadvantages, depending on the personal economic situation, the average person only chooses pneumatic tires, pneumatic tires are economical and affordable. Vacuum tires** are higher, better quality, and easy to use. Tires are a major component in vehicle transportation, in addition to their own weight and cargo weight are all borne by tires, so in daily driving, it is necessary to constantly check and maintain maintenance and maintenance rotation installation work.

to ensure safe driving.

Which is better, vacuum tires or pneumatic tires.

Hello! Friend. Each has its own advantages and disadvantages, depending on the personal economic situation, the average person only chooses pneumatic tires, pneumatic tires are economical and affordable.

Vacuum tires** are higher, better quality, and easy to use. Tires are a major component in vehicle transportation, in addition to their own weight and cargo weight are all borne by tires, so in daily driving, it is necessary to constantly check and maintain maintenance and maintenance rotation installation work. to ensure safe driving.

Vacuum tires are pneumatic tires without internal pressure, with high elasticity and wear resistance, and good adhesion and heat dissipation performance. In fact, vacuum tires are not without inner tubes, but the inner and outer tires are combined into one, in the sidewall of vacuum tires, there is a layer of intimacy between the beads with very good intimacy, instead of the role of the inner tube, the thickness of this secret layer is about 2 3mm, under it, there is also this layer of use. The combination of a self-adhesive layer made of a special mixture of rubber ensures good intimacy between the tire and the wheel web, thus replacing the role of traditional inner tubes.

In this way, the effect of the outer tire lifting the inner tube is that after the tire is inflated, the stop mouth is tightly integrated with the net, which effectively avoids deflating. Compared with traditional tires, vacuum tires can ensure long-term air leakage, long service life, simple structure, light weight, and are conducive to high-speed driving of automobiles.

In addition to the advantage of not running out of gas, it will not be because of the broken tire and can not ride anymore, which is basically a disadvantage, such as the tire is heavier, harder, the grip is almost worse, and the riding is correspondingly heavier than the hollow tire, which is much more laborious, and it is easier to slip and cause accidents on rainy days because of the small grip.

Non-pneumatic tires are tires that achieve shock absorption and cushioning without the help of air pressure. An pneumatic tire is a rubber seal that has an empty pressure gas. When the [k0] body is compressed, the air molecules collide more violently with the container wall, resulting in an increase in air pressure and the formation of macroscopic elasticity.

Until now, no tire has been able to surpass the excellent cushioning performance and low rolling resistance of pneumatic tires.

Non-pneumatic tires, that is, tires that are not inflated, do not rely on empty air, and only use the material and structure of the tire itself to achieve support and cushioning performance.

1.Solid tires. Such tires have been produced for hundreds of years. The main characteristics are large carcass weight, poor elasticity, large rolling resistance and large bearing capacity. It is suitable for large vehicles with slow moving speed and heavy load requirements.

2.Ester tires. The foam solid tire made of polyurethane material has the advantages of beautiful appearance and light weight, and the disadvantages are easy aging, detaching, wear-resistant, and high rolling resistance.

Millions of car purchase subsidies.

Non-pneumatic tires refer to tires that do not rely on air pressure to achieve shock absorption and cushioning performance. Pneumatic tires are sealed with rubber with pressure air, when the air is compressed, the air molecules collide more intensely on the container wall, resulting in an increase in air pressure, forming a macroscopic elasticity, pneumatic tires have superior cushioning performance and low rolling resistance characteristics that no other tire can surpass so far.

Non-pneumatic tires are tires that do not need to be inflated, without the help of air, and only use the material and structure of the tire itself to achieve support and cushioning performance.

1.Solid tires. These tires have been in production for more than 100 years. The main characteristics are large carcass weight, poor elasticity, large rolling resistance, and large load. It is suitable for vehicles with slow movement speed and relatively large load requirements.

2.Ester tires. The polyurethane material is made of foam-like solid tires, which has the advantages of beautiful appearance and light weight, and the disadvantages are easy aging, defetuation, non-wear-resistant, and large rolling resistance.

So far, no tire has surpassed pneumatic tires in terms of superior cushioning performance and low rolling resistance.

2.Non-pneumatic tires are pneumatic tires that help in inflating. They simply utilize their own materials and structures to achieve support and cushioning properties.

3.Solid tires. This tire has been in production for many years. It is characterized by large carcass weight, poor elasticity, large rolling resistance and large bearing capacity. It is suitable for large vehicles with slow moving speed and relatively high hail noise with load requirements.

4.Ester tires are shiren beams. The advantages of polyurethane foam solid tires are beautiful appearance and light weight, but the disadvantages are easy aging, decoupling, easy grinding, and high rolling resistance.
