How to Check Nitrogen Tire Pressure | Ways You Must Know

How to Check Nitrogen Tire Pressure

Many individuals don’t consider their nitrogen tire pressure when driving, but ensuring you have enough in your tires is crucial.

If you need help with how to check the nitrogen tire pressure or how much nitrogen should be in the tires, don’t worry; this article will assist you in finding the answers to these and other concerns.

How to Check Nitrogen Tire Pressure

Now that you know the procedures, it is time to understand how to check the pressure.

How to Check Nitrogen Tire Pressure
  • Discover the required PSI: Your car’s tires should be inflated to the required PSI, or pounds per square inch. This information can be found on the sidewall of your tire or in the owner’s manual for your car.
  • Locate the gauge: To determine the PSI of your tires, you could use a gauge. Most auto supply stores sell this, or you may use a glucometer on your phone.
  • Fill the tires to the required PSI: After getting the gauge, fill the tires to the PSI indicated on the sidewall of the tire or in the owner’s handbook as the necessary PSI.
  • Use a meter stick to check the pressure: After the tires are inflated to the recommended PSI, use a pressure sensor to check the pressure.
  • Compare the thermometer interpretation: If it differs from the recommended PSI, air needs to be added; if it is lower, air must be let out.
  • Observe the pressure: Keep track of your tire pressure by writing it down to check that it is at the recommended PSI.
  • Carry out this procedure again every few months to ensure that the nitrogen pressure in your car’s tires is still at the required PSI.

Do it routinely now that you know how to check your nitrogen tire pressure. It is crucial to maintain the security and functionality of your vehicle.

How to Determine a Tire’s Nitrogen Percentage

There are a few things to look out for if you’re unsure whether the nitrogen in your tires is indeed nitrogen.


How to Check Nitrogen Tire Pressure

There is typically a tag on the sidewall to indicate if a tire is nitrogen inflated.

Color of the valve stem:

The tire’s valve stem is where the air is added or released. If the valve stem is black, nitrogen is probably inside; if it is silver, it is not inside.

Nitrogen PSI:

A nitrogen-filled tire’s recommended PSI is typically higher than one that isn’t. 

Attach the mobile nitrogen analyzer:

If you’re still doubtful, you can fasten a mobile nitrogen analyzer to the valve stem. The tire is most likely inflated with nitrogen if the value is between 80 and 95%.

Get in touch with the seller or technician:

If you’re still doubtful, get in touch with your technician or seller. If your tires are inflated with pure nitrogen, they can confirm it for you.

What Advantages Does Nitrogen Inflation Offer?

Using nitrogen in your car’s tires rather than ordinary air has many advantages.

What Advantages Does Nitrogen Inflation Offer?
  • It requires time: Inflation of nitrogen typically takes longer than that of ordinary air. This results in less frequent checking and air addition.
  • Nitrogen is more stable than ordinary air; therefore, your tire pressure will be more consistent. For factors like tire wear and fuel efficiency, this is crucial.
  • It spills less: Since nitrogen leaks less often from the tire service, you don’t need to refill the air regularly. Both your wallet and your tires will benefit from this.
  • Its eco-friendlier: Since nitrogen inflation doesn’t require fossil fuels, it is also more eco-friendly.
  • It’s secured: Since nitrogen inflation is more reliable and has less leakage than ordinary air inflation, it is generally secure.

With all these advantages, nitrogen inflation is a fantastic tire-inflation option for your vehicle.

Frequently Asked Questions

What is the suggested PSI level for tires with nitrogen fill?

In general, air pressure in tires was 3.5 psi, whereas nitrogen pressure was 2.2 psi. Thus, there is only a 1.3 psi gap between the two approaches. The tires all lost pressure, regardless of the kind of air they contained.

What happens when you fill a tire with nitrogen?

A tire filled with nitrogen will maintain its air pressure longer than a tire filled with ordinary air. When filled with ordinary air, normal tires lose one to two pounds per square inch every month. According to Consumer Reports, nitrogen reduces tire air pressure loss to about one-third of the average loss.

Is nitrogen inflation more ecologically friendly?

Nitrogen tire inflation reduces moisture and oxygen, which prevents the rubber from degrading and prevents corrosion from occurring, unlike compressed air.

Is it safe to use nitrogen inflation?

Nitrogen requires less frequent air additions since it is less likely to leak out of the tire. This is beneficial for both your pocketbook and your tires! Additionally, nitrogen inflation is generally considered safer than ordinary air inflation because it is more stable and does not leak as much.

How do you treat tires with nitrogen filling?

Tires containing nitrogen should be handled similarly to tires containing air. Money is squandered on conventional autos. Increased revenue for a facility providing the nitrogen service is the primary goal of nitrogen refills.


The tire on your car makes a fine choice for nitrogen inflation. It not only lasts longer, but it is more stable and leaks less as well. Additionally, it is safer and more environmentally friendly than simply blowing it up with air. This article has helped to clarify the advantages of nitrogen inflation and how it may assist you in maintaining the best possible condition for your car tires.

Expert Opinion

Using a gauge is the most effective technique to check the pressure of your nitrogen tires. A pressure rating sticker on the side of the tire may also be used if you don’t have a gauge. Pre-ride tire pressure inspection is a must.
