What Is The Difference Between Nitrogen Gas and Air?

Nitrogen vs air in tires

From older to the current time, nitrogen gas is being used to speed up the cars in race rallies, but now people have changed their way and come to know new secrets of science. Now, mechanics recommend only nitrogen gas for tire inflation. Nitrogen is inflammable and does not get heated quickly, so it can save the lives of millions of people in hot weather countries.

As a being mechanic, I only recommend nitrogen for tires. It does not only act against heat but also saves tire life. But you must have to make sure the right pressure for tires. But I am totally against those people who think nitrogen prevents tires from puncturing. To be honest, it is a wrong ideology, but this is true it increases the tire life significantly. 

Now, the trend of using nitrogen gas for tire inflation has been increasing dramatically. Super countries like Japan, the USA, and Europe have adopted this technique to reduce the risk of a tire explosion. Human life is important to us and as a being a mechanic we recommend only nitrogen for tires.


What is the difference between air and nitrogen gas?

Although air contains nitrogen gas but contains oxygen gas as well. As we know oxygen gas is flammable gas so due to this it gets heat up so rapidly and increases the risk of tire explosion in hot weather conditions. But on the other hand, only nitrogen is a non-flammable gas and does not get heated up. When there is no heat inside the tire, so definitely it will not only save the tire’s life but also will reduce the chance of tire explosion.

So, in a nutshell, nitrogen is the best option as compared to air. I will go for nitrogen gas-filled tires personally, and it is the trend these days that we must have to adopt. And it is not only the trend of using nitrogen for tires but also important for the safety of drivers. Nitrogen is not hazardous for us, but it is safer to use as compared to air. I will give no marks to air but full marks to nitrogen as a being a mechanic.


  • Does nitrogen gas prevent tire corrosion?

Definitely yes, Nitrogen does not get heated quickly, and it is non-flammable gas, and apart from the resistance of road heat is the worst enemy of tires. And when tires get heated up, these tires will explode only due to heat. So, the only solution to this problem is to use nitrogen gas for tires, but with the right pressure. The study of automotive tells us that the lives of tires can be increased by using nitrogen for tires inflation.


Does Nitrogen gas inflation react against punctures?

No, it does not. It is a wrong sense some people have that nitrogen gas prevents tires to get punctured. It means nitrogen does not stop valve leakage or prevent punctures. But nitrogen off course increases tires’ lives and increases drivers’ safety.


  • Do we not need to check tires pressure when filling with nitrogen gas?

Of course, we do need to check tires pressure whether we are filling tires with air or with nitrogen, it is mandatory to check tires pressure once or twice a month. When we have a holidays plan then we must have to check the tire pressure before leaving for the journey to have a safe trip. 


  • Is it necessary to fill nitrogen gas when refilling tires?

Yes, when your tires are filled with nitrogen then, it is necessary to refill with nitrogen according to the required pressure of tire inflation.


Can wrong pressure cause damage to a car’s tires?

Yes, it does affect the tires, when we don’t care about the right pressure of tire inflation. If the required pressure of tires is not maintained, then it can cause real damage. So, it is compulsory to maintain the right pressure of tire inflation.
