Why do car tires need to be filled with nitrogen?

1. Improve the stability and comfort of tire driving.

Nitrogen is almost an inert diatomic gas with chemical properties.

It is extremely inactive, the gas molecules are larger than the oxygen molecules, not easy to heat up and shrink, the deformation amplitude is small, and the speed of its penetration of the tire wall is about 30 40% slower than the air, and it can maintain stable tire pressure.

Improve the stability of tire driving and ensure driving comfort; The audio conductivity of nitrogen is low, equivalent to 1 5 of ordinary air, and the use of nitrogen can effectively reduce the noise of tires and improve the quietness of driving.

2. Prevent punctures and run-offs.

Tire puncture is the number one killer in road traffic accidents, according to statistics, 46% of traffic accidents on the highway are caused by tire failure, of which tire puncture accounts for 70% of the total number of tire accidents. When the car is driving, the tire temperature will increase due to friction with the ground, especially when driving at high speed and emergency braking, the gas temperature in the tire will rise rapidly, and the tire pressure will increase suddenly, so there will be a possibility of a puncture. The high temperature leads to the aging of tire rubber and fatigue strength.

Dropping, severe tread wear, and another important factor that can lead to a puncture. Compared with general high-pressure air, high-purity nitrogen has a coefficient of thermal expansion because it is oxygen-free and contains almost no water and no oil.

Low, low thermal conductivity, slow heating, reduce the speed of tire heat accumulation, and other characteristics, so it can greatly reduce the probability of puncture.

3 Extend the life of your tires.

After the use of nitrogen, the tire pressure is stable and the volume changes small, which greatly reduces the possibility of irregular tire friction, such as crown grinding, shoulder grinding, and eccentric grinding, and improves the service life of the tire; The aging of rubber is caused by the oxidation of oxygen molecules in the air, and its strength and elasticity decrease after aging, and there will be cracking, which is one of the reasons for the shortening of the service life of tires. The nitrogen separation device can greatly remove oxygen, sulfur, oil, water and other impurities in the air, effectively reduce the oxidation degree of the tire lining and the phenomenon of rubber corrosion, and will not corrode the metal rim.

This extends the service life of the tires and greatly reduces the condition of rust on the rims.

4. Reduce fuel consumption and protect the environment.

The lack of tire pressure and the increase of rolling force after heating will cause the fuel consumption of the car to increase; In addition to maintaining stable tire pressure and delaying the decrease in tire pressure, nitrogen is dry and does not contain oil or water, low thermal conductivity, and slow heating, which reduces the increase in temperature when the tire is walking, as well as the improvement of small deformation and grip, etc., and reduces the rolling resistance, so as to achieve the purpose of reducing fuel consumption. The relevant departments in the United States have conducted a comparative experiment of nitrogen-filled and air-filled tires, and the statistical results after the experiment show that the nitrogen-filled tires run 26% more mileage than the air-filled tires. Nitrogen-filled tires can be inflated according to the designed tire pressure, which can achieve the fuel consumption index of the car design.

Experiments have proved that nitrogen-filled tires are 2-10% more fuel-efficient than air-filled tires. Effectively reduces air pollution. Brazilians have practiced that nitrogen tires have traveled 50,000 kilometers without needing to be refilled.

Nitrogen-filled tires are more resistant to wear than air-filled tires, and the average mileage of nitrogen-filled tires is 48% more than air-filled tires that break before the tread loss target is reached

Because the general tire inflation uses compressed air, it contains moisture and oil, combined with the oxygen in the air to oxidize the tire, which accelerates the aging of the tire and the corrosion of the steel rim, resulting in valve leakage and tire leakage, resulting in unstable tire pressure. Nitrogen, on the other hand, is dry and clean, contains no water or oil, and does not oxidize tires and corrode the rims. Extend the life of your tires.

In addition, the penetration rate of nitrogen in the tire is low, which can keep the tire pressure stable for a long time. Reduce the chance of puncture and increase the safety of the vehicle. The disadvantage is that once the tire is flat, it will be repaired by a professional repair shop, and the cost is higher, followed by the cost of tire inflation is relatively high.

As a car tire, it is good to fill the wall with nitrogen.

This is because there are many benefits to nitrogen. First of all, it can reduce punctures, so that our personal safety is guaranteed. Second, it increases the service life of the tire, because the use of nitrogen makes the tire pressure more stable, so the irregular friction of the tire is reduced and the life of the tire is longer.

This is not necessary, you can give it a look. Seventy-nine percent of the air is nitrogen, and only 21 percent of the rest is other gases. Even if you fill nitrogen, you can only fill it up to 20 percent, and it can reach more than 90 percent. So it's useless, it's just a hype.

What kind of gas are car tires filled with? Air or nitrogen?

Hello, it is okay for tires to be filled with nitrogen. Fiber leakage nitrogen is an inert gas, which is extremely inactive in nature, and the gas molecules are larger than oxygen molecules, which is not easy to shrink and deformation is small. It penetrates the tire wall 30-40% slower than air, keeping the tire pressure stable.

It has the following advantages:

1.The audio conductivity of nitrogen is low, equivalent to 1 5 of air, and the use of nitrogen can effectively reduce tire noise and improve driving quietness.

2.Compared with general high-pressure air, high-purity nitrogen has a low coefficient of thermal expansion, low thermal conductivity, and slow heating because it is oxygen-free and almost does not contain water and oil, which reduces the speed of tire heat accumulation, and has the characteristics of non-flammable and non-combustion, so that the probability of puncture is effectively reduced.

3.Nitrogen-added tires have less moisture content, so aluminum alloy steel rims and iron steel rims are not easy to rust and corrode, and tires are not easy to oxidize.

Nitrogen tires can improve driving safety and comfort, and extend the service life of tires.

Hope it helps!

Nitrogen stabilization is indeed a little better than disturbing the air, but it is not very useful, if you want to stabilize the tires, you still have to choose a slow resistance product from a big brand such as Pirelli or Goodyear. Mu hunger.

OK. Nitrogen is an inert gas, dry and clean, with low permeability, and is widely stored in the air of clump tung. It will not expand and contract due to the change of external temperature.

After the tire is filled with nitrogen, the tire pressure is extremely stable, especially when driving at high speed, the tire continues to expand and contract circumferentially, the deformation increases, the wear is intensified, and the high temperature generated will cause certain safety hazards to high-speed driving. After nitrogen is heated, the expansion coefficient is low, the permeability is low, and it is not easy to leak, which reduces the seepage puncture caused by the increase of pressure when heated.

Friends, have you ever thought about this question? Today's car tires are generally filled with compressed air, so can they be filled with nitrogen? The answer is yes, because nitrogen is an inert gas, dry and clean, with low permeability, and is widely stored in the air.

Moreover, there are many benefits of nitrogen filling that cannot be compared with air filling. Let's talk about the benefits and see if you think of them!

The first benefit is that nitrogen-filled gas can reduce the chance of a puncture. When the car is driving at high speed, the tire will continue to expand and deform circumferentially, causing the internal gas to expand by heating, which is one of the reasons for the puncture. The expansion coefficient of nitrogen is lower when heated, and the tire pressure of the tire with nitrogen is more stable and less prone to puncture.

The second benefit is that it can extend the life of the tires. It is also because the tire pressure is more stable after adding nitrogen, so that the tire deformation during driving is smaller, and the friction is also smaller, which invisibly improves the tire life. In addition, the air-filled tires oxidize faster, because there are impurities such as oxygen, oil, and water in the air, and the tires should be vacuumed before filling with nitrogen, and then filled with nitrogen, which can squeeze out these impurities and reduce the aging rate of rubber.

The three benefits of the first world are reduced fuel consumption. Insufficient tire pressure will increase the rolling resistance of the tire, fuel consumption will increase, and the air-filled tire cannot increase the tire pressure too much, after all, the problem of thermal expansion must be taken into account. If nitrogen is added, the coefficient of thermal expansion is relatively low, and relatively speaking, it is allowed to add more sufficiently, so that the tire pressure during driving is more stable and disturbed, and fuel consumption is reduced.

Filling your tires with nitrogen has so many benefits, did you want to go back to Jane before? Of course, the ** filled with nitrogen is definitely more expensive, but it is not to the extent of outrageous, if you think it is fun, you can try it.

OK. Nitrogen stool slag gas is an inert gas, dry and clean, with low permeability, and is widely stored in the air. It will not expand and contract due to the change of external temperature.

After the tire is filled with nitrogen, the tire pressure is extremely stable, especially when driving at high speed, the tire continues to expand and contract circumferentially, the deformation increases, the wear intensifies, and the high temperature generated will cause certain safety hazards to high-speed driving. After nitrogen is heated, the expansion coefficient is low, the permeability is low, and it is not easy to leak, which reduces the probability of puncture caused by the increase of pressure when heated, and increases the safety of vehicle driving.

As follows:

1. The benefits of nitrogen filling in automobile tires: improve the stability and comfort of tire driving, prevent puncture and lack of air, prolong the service life of tires, reduce fuel consumption, and protect the environment.

2. The disadvantages of nitrogen filling in automobile tires: tires need to be vacuumed before filling nitrogen, but usually 100% vacuum can not be pumped, and vacuum will deform tires, and it will also cause steel wire deformation, and the cost of tire nitrogen filling is higher.

Introduce. Nitrogen is an inert gas, with low permeability in the tire, which can keep the tire pressure stable, reduce the probability of puncture, prolong the life of the tire, and reduce the vibration of the tire on the uneven road surface, so that the vehicle can drive smoothly.

It also has a low volume conductivity function, which greatly reduces the noise generated when the tire rubs against the ground, etc. Especially in hot climates, nitrogen tires can show their advantages on the highway.

It's okay to inflate tires with nitrogen. Nitrogen is an inert gas, the nature is extremely inactive, the gas molecule collapse is larger than the oxygen molecule, it is not easy to shrink, and the deformation amplitude is small. It penetrates the tire wall 30-40% slower than air, keeping the tire pressure stable. It has the following advantages:

1.The audio conductivity of nitrogen is low, equivalent to 1 5 of air, and the use of nitrogen can effectively reduce tire noise and improve driving quietness.

3.Nitrogen-added tires have less moisture content, so aluminum alloy steel rims and iron and steel source rings are not easy to rust and corrode, and tires are not easy to oxidize.

Nitrogen tires improve driving safety and comfort, and extend the life of your tires.

Nitrogen is indeed a little better than air, but it is not very useful, and if you want to stabilize your tires, you still have to choose products from big brands such as Pirelli or Goodyear.
