Can filling a tire with nitrogen prevent a puncture?

1. Improve the stability and comfort of tire driving. Nitrogen is almost an inert diatomic gas, the chemical properties are extremely inactive, the gas molecules are larger than the oxygen molecules, not easy to expand and contract, the deformation amplitude is small, the speed of its penetration of the tire wall is about 30 40% slower than the air, it can maintain stable tire pressure, improve the stability of tire driving, and ensure the comfort of driving; 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. Flat tires are the number one killer in road accidents. According to statistics, in.

Tyre failure is the result of 46% of highway traffic accidents, with punctures accounting for 70% of all tyre 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, the decrease of fatigue strength, and the severe wear of the tread, which is an important factor that may cause a puncture.

Compared with general high-pressure air, high-purity nitrogen has the characteristics of low thermal expansion coefficient, low thermal conductivity, slow heating, reduced tire heat accumulation, and can greatly reduce the probability of puncture because it is oxygen-free and almost water-free, oil-free, low thermal expansion coefficient, low thermal conductivity, slow heating, and reduced the speed of tire accumulation.

3. After the use of nitrogen to extend the service life of the tire, the tire pressure is stable and the volume changes are small, which greatly reduces the possibility of irregular tire friction, such as crown grinding, shoulder grinding, and eccentric wear, which 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, will not corrode the metal rim, prolong the service life of the tire, and greatly reduce the rust of the rim.

4. Reduce fuel consumption and protect the environment. The lack of tire pressure and the increase of rolling resistance after heating will cause the fuel consumption of the car to increase; In addition to maintaining stable tire pressure and delaying the decrease of tire pressure, nitrogen is dry and oil-free, water-free, low thermal conductivity, and slow heating, which reduces the increase in temperature when the tire is walking, as well as the small tire deformation and improved grip, etc., reducing the rolling resistance, so as to achieve the purpose of reducing fuel consumption.

Many car owners are fooled that filling tires with nitrogen can avoid punctures, is nitrogen useful? If you want to achieve tire safety, you must start from these aspects.

Hello, it is okay for tires to be filled with nitrogen. Nitrogen is an inert gas.

The nature is extremely inactive, the gas molecules are larger than the oxygen molecules, not easy to shrink, and the deformation amplitude is small. It penetrates the tire wall 30-40% slower than air and maintains 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 to general high-pressure air, high-purity nitrogen has a coefficient of thermal expansion because it is oxygen-free and contains almost no moisture and oil.

Low, low thermal conductivity, slow heating, reduce the speed of tire heat accumulation, with non-flammable and non-combustible characteristics, so that the probability of puncture can be 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 improve driving safety and comfort, and extend the life of your tires.

Hope it helps!

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.

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

The advantage of adding nitrogen to tires is that it can maintain tire pressure stability, reduce the probability of puncture and fuel consumption; It can also effectively reduce the noise of tires and improve the quiet comfort of riding; It can also reduce the possibility of irregular friction of tires and delay the aging of tire rubber. The time for a tire nitrogen change is uncertain, generally check the tire pressure at least once a month, and when the tire pressure is lower than the normal range, it needs to be replenished in time.

Nitrogen itself is an inert diatomic gas, and its thermal conductivity is lower than that of air, so it will not be affected too much when heated, and its penetration rate into the tire wall is about 30 to 40% slower than that of air. Even when driving at high speeds, it can ensure that the tires have good tire pressure stability and stabilize the tire pressure, so the probability of tire puncture can be reduced and driving safety can be improved;

Because the tire pressure of nitrogen-filled tires is relatively stable, and the audio conductivity of nitrogen is relatively low, about 1 5 of ordinary air, so the use of nitrogen can effectively reduce the noise of tires. As a result, nitrogen-filled tires can improve the quiet comfort of tires.

A large reason why rubber ages is because the oxygen in the air reacts chemically with the rubber and the steel rim, resulting in tire cracking. If the tire is filled with nitrogen, because the molecular activity of this gas is relatively small, it can not only greatly reduce the possibility of irregular friction of the tire, but also is less prone to oxidation reaction than air, so as to delay the aging of tire rubber; And it can also reduce the possibility of rust on the rim.

If the tire pressure is insufficient, it will lead to an increase in the contact surface of the tire, and the friction will increase, which will naturally directly affect the fuel consumption of the car. The use of nitrogen tires can well maintain the stability of tire pressure and avoid the phenomenon of increased fuel consumption caused by unstable tire pressure. In addition, the low thermal conductivity of nitrogen return air can effectively reduce the increase in temperature of tires during high-speed operation, which reduces the wheel resistance of tires to a certain extent, and also reduces fuel consumption to a certain extent.

Nitrogen filling tires has advantages and disadvantages, among which the most serious consequence of nitrogen filling is that it may damage the tires, because nitrogen filling needs to be vacuumed, and the tires will be deformed, and the inside of the tires is composed of steel wire curtains, so nitrogen filling may deform the tire wires and damage the tires. In addition, the nitrogen filled into the tires is not 100% pure, because a small amount of air remains in the tires, so the nitrogen purity of the tires can only reach 95 - 98%.

Nitrogen filling does have a certain effect in theory, but the gimmick is greater than the actual effect, and it is not so godly. A healthy tire or a cheap tire that has not aged, as long as our tire pressure is normal, it is almost impossible for us to get a puncture due to gas expansion. It is important for us to maintain good habits and pay attention to the wear and tear of tires at all times, so as to effectively reduce the chance of punctures.

1. Improve the stability of tire driving and reduce noise.

2. Effectively prevent the burst of the tire.

3. Extend the service life of tires.

1. Nitrogen is almost an inert diatomic gas, the chemical properties are extremely inactive, the gas molecules are larger than the oxygen molecules, not easy to expand and shrink in heat, the deformation amplitude is small, and the speed of penetrating the tire wall is about 30% 40% slower than the air, so that the tire pressure drop rate is greatly reduced, the normal tire pressure can be maintained for a long time, and the vibration of the tire on the uneven road surface is reduced, and the stability of the tire driving is improved. Moreover, the audio conductivity of nitrogen is low, which is equivalent to 1 5 of ordinary air, which greatly reduces the noise generated when the tire rubs against the ground and improves the tranquility of driving behind the road.

2. When the car is driving, the tire temperature will increase due to its friction with the ground, especially when driving at high speed and emergency braking, the gas temperature in the tire will rise rapidly, the tire pressure will increase suddenly, and there will be a possibility of a puncture. In addition, high temperature leads to the aging of tire rubber and severe tread wear, which is also an important cause of puncture. Compared with air, nitrogen has a low coefficient of thermal expansion, low thermal conductivity, and slow heating, which reduces the rate at which the tire gathers heat, so it can greatly reduce the chance of puncture.

3. The oxygen in the air will oxidize with the tire rubber and steel wire, which will cause the rubber and steel wire to age, shortening the life of the tire. Due to its low molecular activity, nitrogen is not easy to chemically react with the rubber and steel wire of tires, which can delay the aging of rubber. Scientists in the United States have done a comparative test of nitrogen-filled and air-filled tires, and the test results show that nitrogen-filled tires can run 26% more mileage than air-filled tires.

In addition, the air filled into the tires contains moisture, which can easily corrode the steel rims, and the dry nitrogen gas can also protect the inside of the rims from oxidation or corrosion.

Is there any benefit to filling tires with nitrogen, which can prevent punctures, mainly because nitrogen is an inert gas, which is extremely inactive in chemical properties, and is not easy to expand and contract like air, so that the tire pressure will be relatively stable and not easy to increase with the increase in temperature, which greatly reduces the occurrence of punctures; In addition, due to the heat generated by the friction between the tires and the ground during driving, the friction of the brake pads during braking will produce a lot of heat, and the heat will eventually be transmitted to the tires and the air in the tires through the wheel shells, and the continuous compression and stretching of the sidewall of the tires will also produce heat. If the tire is filled with nitrogen, due to the low thermal conductivity of nitrogen, the temperature of the tire carcass is not easy to rise quickly, and the occurrence of punctures can also be reduced.

In addition, the following benefits of filling tires with nitrogen:

1. Reduce tire noise when the car is moving

Because nitrogen is an inert gas, its audio conductivity is relatively low, only equivalent to 1 5 of air, so tire nitrogen filling can effectively reduce the noise of tires. Of course, if you switch to silent tires, the noise reduction effect will be better.

2. Extend the service life of tires

Rubber is easy to age, the root cause of the cherry blossom is caused by the oxidation of oxygen in the air, and the high temperature will also lead to the aging of rubber, its strength and elasticity will be greatly reduced after aging, accompanied by cracking, which directly affects the service life of the tire. Prevent punctures?

Filling tires with nitrogen is good for tires. Compared with air filling, filling the nitrogen will reduce the risk of puncture to a certain extent. At the same time, it can also delay the aging of tires.

Nitrogen is an inert gas. The physical and chemical properties are inactive. At the same time, the expansion coefficient of thermal expansion and cold contraction of nitrogen is low. Therefore, after the tire is filled with nitrogen, the tire pressure in the cold and hot states does not change much, so it is not easy to cause a puncture.

The nitrogen content in the atmosphere is almost 78%. So nitrogen production is also very simple. It is to use a molecular sieve to sieve the oxygen out.

The molecular weight of nitrogen N2 is 28 and that of oxygen O2 is 32. Oxygen is slightly larger. Nitrogen machines are also very cheap, and the big brands of nitrogen machines used in general car tire stores are only two or three thousand yuan.

The benefits of nitrogen filling in automobile tires: 1. Improve the stability and comfort of tire driving; 2. Prevent punctures and run-offs. 3. Extend the service life of tires. 4. Reduce fuel consumption and protect the environment. Disadvantages of filling car tires with nitrogen:

Tires need to be vacuumed before filling nitrogen, but usually 100% vacuum can not be pumped, vacuuming will deform the tire, and will also cause deformation of the steel wire, and the cost of nitrogen filling in tires is high.

Because nitrogen is an inert gas, or the permeability of the potato in the tire is low, it can keep the tire pressure stable, reduce the probability of puncture, prolong the tire life, and reduce the vibration of the tire on the uneven road surface, so that the vehicle runs smoothly, and it also has the function of low volume conductivity, which greatly reduces the noise generated when the tire rubs against the ground and so on. Especially in hot climates, nitrogen tires can show their advantages on the highway.

The advantage of nitrogen inflation in the tires is that it can reduce the speed of tire heat accumulation and keep the tire pressure stable, thereby reducing the probability of puncture and improving the safety of driving; Moreover, because the tire pressure is stable and the audio conductivity of nitrogen is low, it can improve driving stability and silent comfort; It can also delay the aging of rubber and prolong the service life of tires; In addition, it can also reduce the fuel consumption of the waiter.

Nitrogen filling tires has advantages and disadvantages, among which the most serious consequence of nitrogen filling is that it may damage the tires, because nitrogen filling needs to be vacuumed, and the tires will be deformed, and the inside of the tires is composed of steel wire curtains, so nitrogen filling may deform the tire wires and damage the tires. In addition, the nitrogen charged into the tire is not 100% pure, because there will be a small amount of air left in the tire, so the nitrogen purity of the tire can only reach 95 - 98%.

Hello, the benefits of adding nitrogen to tires are that they can maintain tire pressure stability, reduce the probability of puncture and fuel consumption; Limb stare can effectively reduce the noise of tires and improve the quiet comfort of riding; It can also reduce the possibility of irregular tire friction and delay the aging of tire rubber. The main reason for these benefits of nitrogen is that nitrogen is an inert gas with low thermal and audio conductivity. Pretend to be the source.
