Can You Put Air with Nitrogen Together in Tires?

Many people like to add nitrogen into our wheels, and what occurs if you must fill up the nitrogen wheels after they lose a bit of pressure yet all you possess is compressed air? So, can you really put nitrogen with air together in your tires?

The straightforward response is that both nitrogen plus air may be combined in the wheels. The two gasses won’t interact chemically in a harmful way. The performance reduction provided by nitrogen wheels is the sole drawback.

How risky is it to put air plus nitrogen in wheels?


In tires, combining nitrogen with air is absolutely secure. In fact, mixing is preferable than running with low pressure to avoid damaging your tires. Wheels are intended to function at a variety of tensions. If this inflation range goes above or not maintained, the tires may wear unevenly, degrade more quickly than normal, and have a negative influence on fuel efficiency.

In addition, nitrogen is already present in the ambient air. Nitrogen makes up 78% of air, followed by oxygen as 21 percent, vaporized water at 1%, and trace quantities of rare gasses like neon or argon towards the very end. 

Therefore, strictly speaking, air-filled wheels are a combination of gasses, including nitrogen. The sole drawback of combining pure nitrogen using air is when efficiency is somewhat reduced, although not much more compared to with wheels that are normally inflated with air.

How Nitrogen While Not Simply Air to Start with First Place?

Everything is based on chemistry and stress. As was already said, proper tire pressure is essential for healthy, long-lasting tires. A healthy, long-lasting tire is the result of many things.

Wheel symmetry, wheel equilibrium, and tire inflation are the 3 main considerations. The wheel will be controllable, even wear when these 3 conditions are satisfied. Further on that afterwards, but maintaining optimum tire pressure can also save fuel usage.

So what role does nitrogen have? Simply put, pure nitrogen preserves the proper tire inflation more effectively than regular air, providing you with all the advantages associated with the optimal tire inflation. You inquire, “Why?” In any case, here is where the chemical aspect is involved. All tires eventually experience gas leakage or slow leak since the gasses penetrate the rubber

So, yeah, you possess leaks everywhere, but they are gradual and regular. Nitrogen penetrates rubber with a somewhat slower rate—about 40% slower. Longer-lasting tire inflation is maintained by the slower air loss.

In addition, when oxygen seeps into the wheel, it adversely interacts with rubber. The wheel will eventually deteriorate as a result of this response, known as a thermo-oxidative cycle.

Although others contend that the groove is more inclined to wear out first and the resultant deterioration is insignificant. Pure nitrogen’s thermal characteristics are another reason why it sustains pressure more effectively than the atmosphere. 

Tire Pressure Monitor

The wheel pressure monitor can turn on as a result of the colder weather. The reason for this is since as warmth drops, air molecules grow closer together. The levels of pressure remain lower even though no air wasn’t lost. This impact is much lessened when using pure nitrogen. Actually, nitrogen is considered the ideal gas for racing vehicles and airplanes due to its thermodynamic characteristics.

As was already established, compressed air often contains vaporized water in addition to other elements. There are problems because of the water within the wheel. As temperatures vary, it firstly affects how pressure shifts.

Despite the absence of moisture vapor, temperature-related pressure variations continue to exist in ordinary air; nonetheless, the water has a significant impact on these alterations.

Additionally, both steel as well as aluminum rims are susceptible to corrosion due to the air’s moisture content. Since there is no moisture in a nitrogen-only gas, thus is no chance of corrosion that cannot be observed.

Why do properly inflated tires use less fuel?

As was already discussed, low tire inflation will reduce fuel efficiency. Tire roll, often known as tire rolling resistance, being the phrase used to describe this. The motor must distribute its power to the tires so as to keep an automobile moving along at a consistent speed across an area. Tire roll is the name for this vitality. 

The role of the wheel is to transmit energy through the road, and this pushes against and moves the car forward. The tire gradually deforms when it presses towards the surface of the road.

When seeing a drag driving automobile in a pause, this distortion may be observed plainly. gasoline is spent for every little amount of displacement; the more gasoline is lost, the lesser the tire inflation should be. A further incentive for reviewing your user handbook or the doorjamb label to make certain that the wheels are inflated to the proper PSI.

How should I fill my tires with nitrogen?

Nitrogen-filled wheels are unquestionably superior. How can you insert pure nitrogen inside your wheels? Purified nitrogen can boost your tire inflation stability, reduce tire upkeep, improve your fuel efficiency, and reduce your chance of rusting, though certain situations might mean buying another pair of rims. 

Although you could just visit a car store, tire shop, or service location, you can also do things privately if you so want. But you must have the required tools. You will require:

Getting a nitrogen cylinder loaded

  • Raise jack 
  • The required tubes and connections, including a digital wheel inflator. 
  • Its nitrogen analyzer and green nitro lock covers are further options.

Nevertheless, since nitrogen testers may be expensive, you might save money by filling the wheels at a dealership, wheel shop, or petrol pump the initial time, subsequently refilling them on your own afterwards.


The quick answer is that you may combine air with nitrogen into the wheels. This means that certain of the advantages associated with having only nitrogen inside the wheels will be lost.

Furthermore, if that nitrogen content drops below 92%, then may need to cleanse the air once again. Nevertheless, irrespective of whether you fill up the wheels with air rather than nitrogen, one should do so for security concerns if they have inadequate pressure.
