The main benefit of nitrogen-filled tires is that the loss of tire pressure is slower, because the gas in the tire escapes more slowly than air does. With more stable tire pressure, the thinking goes, you’ll get better gas mileage and get full tire life since you’re always rolling on fully inflated tires.
- Does nitrogen make a difference?
- But for the most part, nitrogen makes absolutely no difference when it comes to a loss of pressure caused by tire punctures, tire bead leaks, valve leaks, or other mechanical leaks. There’s no discernible benefit over air-filled tires, and that includes performance factors such as rolling resistance, fuel economy, and tire aging.
- Are your tires filled with nitrogen?
- We often assume that tires are simply filled with air, and most of the time they are. But, some vehicles have their tires filled specifically with nitrogen. There are some advantages to using nitrogen over regular air, but there are also plenty of myths regarding fuel economy and rolling resistance.
- Does inflating tires with nitrogen affect rolling resistance?
- The lab report from NHTSA also found that “inflating with nitrogen in place of air had little or no direct effect on tire rolling resistance performance.” Rolling resistance is a factor in fuel economy, and it is something that is part of CR’s routine tire testing.
- What are the advantages and disadvantages of nitrogen?
- One of the advantages of nitrogen is that it may help your tires remain inflated for longer. That is because on a molecular level, nitrogen moves more slowly than the compressed air typically used to fill tires. The nitrogen molecule is also larger than regular air, which helps with this effect as well.

Is it okay to fill tires with nitrogen?
To be clear, inflating tires with nitrogen is not harmful. Moreover, the PSI stays steady in the long term. (Tires filled with regular air lose pressure through permeation a little more quickly.)
- Should you fill your tires with nitrogen or air?
- An accurate pressure gauge can help you maintain proper tire pressure, whether using nitrogen or air. Filling your tires with nitrogen might provide benefits in these areas: Gas Mileage. Properly inflated tires can improve gas mileage, whether they are filled with air or nitrogen.
- Does nitrogen leak from tires?
- Myth: Nitrogen does not leak from tires as quickly as compressed air, and therefore maintains proper tire pressure for a longer time. Fact: Tires naturally lose small amounts of pressure over time whether they are filled with compressed air (oxygen) or nitrogen.
- Is inflating tires with nitrogen a waste of money?
- It might even be considered a frivolous waste of money. To be clear, inflating tires with nitrogen is not harmful. Moreover, the PSI stays steady in the long term. (Tires filled with regular air lose pressure through permeation a little more quickly.)
- Does purified nitrogen make sense for car tyres?
- Purified nitrogen has been used to inflate tyres on aircraft and racing cars for many years but does it really make sense for ordinary car tyres? The air we breathe, and the compressed air normally used to inflate tyres, is mostly nitrogen anyway – 78% Nitrogen, 21% Oxygen and 1% other gases.
What are the disadvantages of nitrogen-filled tires?
Nitrogen in tyres: Disadvantages It’s more expensive than normal air or oxygen, which you can even fill up free of cost. Maintenance: You have to maintain the nitrogen-filled tyres, which can be tricky at times. You cannot fill normal air once you start using nitrogen.
- What happens if you put nitrogen in your tires?
- The larger, slower-moving nitrogen molecules seep out of the tire more slowly, and some experts say this can help keep tires inflated longer. Using a combination of nitrogen and air in your tires won’t harm them, but it might reduce the effectiveness of the nitrogen fill and cause your tires to deflate more quickly than if you used pure nitrogen.
- What are the disadvantages of nitrogen?
- Disadvantages of Nitrogen: So, it needs to be considered seriously against the zero cost of oxygen. 2) Maintenance of nitrogen filled tyres is also quite tricky because once you have filled nitrogen inside your tyres, it is necessary that you have to use only nitrogen whenever you are up for an air filling.
- What are the benefits of nitrogen tire inflation?
- Nitrogen tire inflation can be expensive and high maintenance, but increase gas mileage and tire life, among other advantages. A properly inflated tire wears slower. If a nitrogen filled tire does not lose pressure as quickly you can expect longer tire life. Oxidation is blocked. Oxygen causes oxidation.
- How to maintain nitrogen filled tyres?
- 2) Maintenance of nitrogen filled tyres is also quite tricky because once you have filled nitrogen inside your tyres, it is necessary that you have to use only nitrogen whenever you are up for an air filling. In case you add normal compressed air, it will make the introgen ineffective of its benefial properties.
Can I mix air and nitrogen in tires?
Using compressed air in tires that have previously been filled with nitrogen will not harm your tires. While mixing the two won’t result in an adverse chemical reaction, it will dilute the purity of the nitrogen and lessen its effectiveness.
- Can you add air to nitrogen-filled tires?
- In that situation, adding air to your nitrogen-filled tires is fine. Air is composed of 78 percent nitrogen, 21 percent oxygen, and 1% other gases. There will be no chemical reaction if you mix this mixture with the pure nitrogen in your tires.
- Can you mix regular air and nitrogen?
- Actually you can mix regular air and nitrogen, but with risks. Some facts. Nitrogen has a larger number of molecules than air, so it can maintain tire temperature at bay. For the same reason, the elasticity of the tire also is also better. The nature of molecules contained in nitrogen is the ability to reduce scraping and wear inside.
- What are nitrogen tires?
- Nitrogen tires are filled with nitrogen instead of, or in addition to, regular air. The larger, slower-moving nitrogen molecules seep out of the tire more slowly, and some experts say this can help keep tires inflated longer.
- How do you keep air out of tires?
- The only way to retain the benefit of the air-nitrogen mixture is to fill up the tires with regular air and then top up with nitrogen every time they get deflated. In this way, air will be completely removed from the tires at one point. Just topping up with nitrogen one or two times won’t cut it.
Are tires better with air or nitrogen?
Nitrogen causes less wear and tear to the tires than air. Nitrogen is dry air without the presence of oxygen. It is free of moisture, leading to fewer temperature changes in the tires, which helps maintain tire condition over extended periods. This is highly beneficial for speed racers.
- Are nitrogen-filled tires better than ambient air?
- Cold air pressure readings are going to be more accurate. In this scenario, nitrogen-filled tires are advantageous because nitrogen gas doesn’t support moisture or combustion. Compared with ambient air – which contains roughly 78 percent nitrogen, 21 percent oxygen, plus miscellaneous gases – pure nitrogen is an inert, non-flammable gas.
- What are the benefits of nitrogen in tires?
- The most prominent benefit of nitrogen is a more consistent pressure, which is important to keep your tires in good shape. Normally, the air will seep out the tires over time, which reduces the pressure.
- Is nitrogen better than regular air?
- Nitrogen is comprised of larger molecules than regular air, making it less susceptible to losing air pressure. To prove this fact, a recent study completed by Consumer Reports compared tires filled with nitrogen to those with regular air. In this study, they used 31 different tires and filled one with nitrogen and the other with regular air.
- Is nitrogen good for your car?
- Many auto pundits suggest that nitrogen will offer a better economy. It is mainly because it seeps from the tires gradually and also contributes to overall tire health. A fully pressurized tire drives well with no hitches. Air-filled tires are prone to air seepage; thus, there is a loss of pressure.
How much longer does nitrogen last in tires?
As such, tires containing compressed air tend to lose about 1-3 PSI per month due to oxygen permeation, leaving the slow-escaping nitrogen behind. Tires inflated with pure nitrogen tend to stay inflated longer—3-4 times as long.
- What happens if you fill a tire with nitrogen?
- A tired filled with nitrogen maintains its air pressure longer than regular air-filled tires. A normal tire with regular air loses approximately one to two pounds per square inch per month. According to Consumer Reports, nitrogen slows down the rate of tire inflation loss to about one-third of regular air pressure loss.
- What type of nitrogen should I use for my tires?
- Racecar Owners: If you own a racecar, then pure nitrogen is the best option for your tires. Track tires benefit the most from 100 percent nitrogen purity because of the minimal pressure change. New Car Buyers: A new car comes with brand new tires filled for the first time.
- What is the difference between air-filled and nitrogen-filled tires?
- Nitrogen-filled tires lose pressure more slowly due to the larger molecule size, reduce oxidation due to the lack of oxygen, improve fuel efficiency, and may prolong tire life. Air-filled tires are more accessible, affordable, compatible with all tires, and allow for easy top-offs and maintenance.
- How often should you top off your tires?
- If you want to keep your tires within one pound per square inch of the ideal pressure, then top off your tires at least four times a year, if not more. Unfortunately, if you need to top off your nitrogen in your tires, you cannot go to your local gas station because regular air dilutes the nitrogen purity.
Do nitrogen tires cost more?
It would cost you anywhere between $70 to $200 when you purchase a new vehicle and want nitrogen-filled tires. You will be paying close to $30to fill tires that have compressed air in them. That’s because the oxygen needs to be removed with multiple nitrogen refills. Topping off will cost you $5 to $7 per tire.
