Can You Put Air in a Nitrogen Tire?

Nitrogen-filled tires are becoming more popular, as they offer a few advantages over traditional air-filled tires.

However, you may wonder if can you put air in a nitrogen tire. The answer is yes, you can put nitrogen in a tire that is already filled with air, and it will provide the same benefits as using nitrogen in a new tire. 

In this blog post, we’ll tell you what you need to know about filling your tires with nitrogen.

We’ll also give you some tips on how to make the switch to nitrogen-filled tires if you’re thinking of making the switch. So, read on to learn more!

What are nitrogen tires and how do they work

What are nitrogen tires and how do they work

Nitrogen tires are filled with nitrogen gas instead of air. This is because nitrogen molecules are larger than oxygen molecules, so they leak out of tires at a slower rate.

In addition, nitrogen does not expand or contract as much as oxygen in response to changes in temperature. As a result, nitrogen-filled tires tend to maintain their pressure longer than regular tires, which can help to improve fuel economy and extend the life of the tires.

While some car dealerships offer nitrogen tire services, it is relatively easy to fill your own tires with nitrogen using an inexpensive kit. Simply attach the kit to your tire valve and let the nitrogen flow in.

Once the tire is filled, check the pressure to ensure that it is within the recommended range for your vehicle. Filling your own tires with nitrogen is a quick and easy way to improve the performance of your vehicle.

Can you put air in tires with nitrogen?

Yes, you can put air in tires with nitrogen. Air is made up of 78% nitrogen, so it stands to reason that you can fill your tires with air without any problems.

In fact, many carmakers recommend using nitrogen to inflate your tires, as it delivers a number of benefits over regular air.

For one, nitrogen molecules are larger than oxygen molecules, so they leak out of tires more slowly. That means your tires will stay properly inflated for longer, improving fuel economy and extending their lifespan. (See How to Fix a Slow Leak in a Tire?)

In addition, nitrogen doesn’t expand and contract as much as air does with changes in temperature, so your tires will maintain a consistent pressure regardless of the weather.

Whether you choose to fill your tires with air or nitrogen, just make sure you check the pressure regularly to ensure they’re safe to drive on.

The benefits of mixing nitrogen in tires

The benefits of mixing nitrogen in tires

There are several benefits of mixing nitrogen in tires, including:

Improved fuel economy

Mixing nitrogen with air in tires can improve fuel economy by reducing the rolling resistance of the tires. The reduced rolling resistance results in less energy being required to move the vehicle, which improves fuel economy.

Additionally, nitrogen-filled tires maintain their pressure for longer than tires filled with air, which also helps to reduce rolling resistance and improve fuel economy.

While the exact fuel economy benefits will vary depending on the vehicle and driving conditions, it is generally agreed that mixing nitrogen with air in tires can lead to significant improvements in fuel economy.

Better tire pressure

Mixing nitrogen with air in tires gives better tire pressure. Nitrogen is less likely to leak out of tires than air, so it can help keep tires inflated longer. In addition, nitrogen molecules are larger than oxygen molecules, so they can help to prevent the tiny holes in tires from leaking air. As a result, mixing nitrogen with air in tires can help to improve tire pressure and extend the life of tires.

Improved safety

Air is a vital component of tires, as it helps to support the weight of the vehicle and maintain tire pressure. However, air alone is not enough to ensure optimal tire performance.

In order to improve safety and handling, many tire manufacturers add nitrogen to their tires. Nitrogen is an inert gas that is less likely to leak out of the tires than regular air.

As a result, tires inflated with nitrogen tend to retain their pressure for longer, providing better support and stability on the road.

In addition, nitrogen-filled tires are less prone to temperature fluctuation, which can cause changes in tire pressure and contribute to blowouts. For these reasons, mixing nitrogen with air in tires can be an effective way to improve safety and performance.

Better tire pressure retention

Nitrogen is an inert gas that is found in the air around us. When nitrogen is combined with oxygen, it forms NO2, which is a gas that is used in car tires.

NO2 helps to improve tire pressure retention by keeping the air in the tire from escaping. The process of nitrogenization helps to keep the tire inflated for a longer period of time, which can improve the lifespan of the tire.

In addition, nitrogen-filled tires tend to run cooler than air-filled tires, which can help to prevent premature wear and tear. As a result, mixing nitrogen with air in tires can give better tire pressure retention and extend the life of the tire.

Eco-friendly

Nitrogen is a safe and eco-friendly gas to fill your tires with for a number of reasons. First, it doesn’t deplete the ozone layer like other gases, such as chlorofluorocarbons (CFCs) used in some aerosol cans.

Second, because it is less reactive than oxygen, it doesn’t create corrosive moisture inside the tire that can lead to weaker tire walls and decreased tire life.

Third, nitrogen molecules are larger than oxygen molecules, so they leak out of tires more slowly. This means that you won’t have to refill your tires as often, which saves time and money.

And finally, because nitrogen is less likely to react with other elements inside the tire, it helps to keep tires cooler, which can improve fuel efficiency. So next time you need to fill up your tires, consider using nitrogen instead of air for a greener option.

Cons of using nitrogen in tires

Cons of using nitrogen in tires

Expensive

While the benefits of using nitrogen in tires are clear, there is one downside: the cost. Nitrogen-filled tires typically cost more than regular air-filled tires.

The extra cost is due to the fact that nitrogen is not found naturally in the air and must be artificially created. As a result, it can be more expensive to fill your tires with nitrogen than with regular air.

However, many experts believe that the long-term benefits of using nitrogen in tires outweigh the initial cost.

Availability

Another downside of using nitrogen in tires is that it can be difficult to find a nitrogen filling station. While most tire shops offer nitrogen-filled tires, not all of them have the equipment to fill tires with nitrogen.

As a result, you may have to drive out of your way to find a place that can fill your tires with nitrogen. However, the number of nitrogen filling stations is increasing as the demand for nitrogen-filled tires grows.

Difficult to DIY

Unlike air, which can be easily filled at home with a pump or compressor, nitrogen requires special equipment to fill tires.

As a result, it is not possible to fill your own tires with nitrogen without the help of a professional.

This can be an inconvenience for some people, as it requires making an extra stop to have your tires filled.

While the cost and availability of nitrogen can be drawbacks, the benefits of using nitrogen in tires are clear. Nitrogen-filled tires provide better tire pressure retention, extended tire life, and improved fuel efficiency.

If you are looking for ways to improve the performance of your vehicle, consider filling your tires with nitrogen the next time you need to inflate them.

How to properly fill your nitrogen tires

How to properly fill your nitrogen tires

It is important to know how to properly fill your nitrogen tires in order to take full advantage of the benefits they offer.

Here are a few tips on how to fill your tires with nitrogen:

  • Make sure the tire shop uses dry nitrogen. Nitrogen that has moisture in it can actually be detrimental to your tires.
  • Check the pressure of your tires before and after filling them. The ideal pressure for most passenger vehicles is between 30 and 35 psi.
  • If possible, have the shop fill all four of your tires with nitrogen. This will help to ensure that your tires are evenly inflated, which can improve handling and fuel efficiency.

Ask the shop if they offer a warranty on their nitrogen-filled tires. Some shops offer a free nitrogen top-off for a certain period of time after you purchase your tires.

Tips for maintaining nitrogen-filled tires

Now that you know how to properly fill your nitrogen tires, it is important to know how to maintain them. Here are a few tips for keeping your nitrogen-filled tires in good condition:

  • Check the pressure of your tires regularly. Nitrogen-filled tires can lose pressure over time, just like regular air-filled tires.
  • Make sure to check the pressure of your tires at least once a month and before long road trips. Be sure to check your owner’s manual for the recommended tire pressure for your vehicle.
  • If you notice that your tire pressure is low, add more nitrogen. Do not add regular air to your nitrogen-filled tires, as this will decrease their performance.
  • Do not overinflate your nitrogen-filled tires. Overinflating your tires can cause them to wear out prematurely.
  • Most experts recommend rotating your tires every 5,000 to 8,000 miles.
  • Have your tires serviced regularly? In addition to regular rotations, it is important to have your tires serviced by a professional on a regular basis. This includes having them balanced, aligned and checked for tread wear. Be sure to follow the recommendations in your owner’s manual for how often to have your tires serviced.

Nitrogen vs air in tires

There are a few key differences between nitrogen and air when it comes to tires. 

Nitrogen is a dry gas, while air contains moisture. This means that nitrogen-filled tires are less likely to develop rust on the inside of the tire.

Nitrogen is also less likely to leak out of tires than air. As a result, tires inflated with nitrogen will retain their pressure for longer, making them less likely to need frequent topping-up. 

Finally, nitrogen-filled tires tend to run cooler than air-filled tires. This is due to the fact that nitrogen molecules are larger than oxygen molecules, meaning they conduct heat less effectively.

For these reasons, nitrogen-filled tires offer a number of advantages over regular air-filled tires. These benefits can include improved fuel efficiency, extended tire life, and better tire pressure retention.

If you are looking for ways to improve the performance of your vehicle, consider filling your tires with nitrogen the next time you need to inflate them.

Why do my tires have green caps?

The green caps on nitrogen-filled tires are used to indicate that the tires have been filled with nitrogen. The caps serve no other purpose.

Does nitrogen affect tire pressure sensors?

No. Nitrogen does not affect tire pressure sensors. Tire pressure sensors (TPS) are devices that measure the pressure inside a tire, and they are unaffected by nitrogen.

The main benefit of using nitrogen in tires is that it is less likely to leak out than regular air, which means that tires will maintain their correct pressure for longer. However, regardless of what type of gas is used to fill tires, all TPS will function in the same way.

How often fill nitrogen tires?

It is best to fill nitrogen tires every 2 to 3 months. This will help to ensure that the tires are always at their optimal pressure, providing the best possible performance.

If you notice that your nitrogen tires are losing pressure more quickly than usual, it may be a sign of a leak in the tire or a problem with the tire valve. In either case, it is best to have the tire checked by a professional as soon as possible.

Does cold weather affect nitrogen-filled tires?

Nitrogen is a gas, and like all gases, it is affected by changes in temperature. When the weather gets cold, nitrogen molecules slow down and take up less space. This can cause the pressure in nitrogen-filled tires to decrease.

The relationship between temperature and tire pressure is a gas law known as Gay-Lussac’s Law. This law states that for every 10 degrees Celsius increase in temperature, the pressure in a sealed container will increase by 1 atmosphere. The same is true for the decrease in temperature.

Nitrogen molecules are larger than oxygen molecules and do not permeate through the rubber as easily. However, because nitrogen is still a gas, it is still affected by changes in ambient temperature.

Cold weather can cause the pressure in nitrogen-filled tires to decrease, just as it would with any other type of tire. Therefore, it is important to check your tire pressure frequently during periods of extreme cold weather.

To compensate for this, it is recommended that you slightly increase the pressure in your tires during cold weather months. Be sure to check your owner’s manual for the recommended tire pressure for your vehicle.

What year did they start putting nitrogen in tires?

In 1963, Goodyear began using nitrogen in tires as a way to improve its performance. The goal was to create a tire that would maintain its pressure better over time, and nitrogen was thought to be the key. The benefits of using nitrogen are that it is less likely to leak out of the tire, and it also helps to keep the tire cooler.

As a result, tires filled with nitrogen can last longer and provide better performance. Today, many tire manufacturers offer nitrogen-filled tires as an option for consumers. While the initial cost may be higher, the long-term benefits can make it worth the investment.

Do nitrogen tires go flat?

All tires, regardless of what type of gas they are filled with, can go flat. However, because nitrogen is less likely to leak out of the tire, it can help to prevent flats. This is because nitrogen molecules are larger than oxygen molecules, so they are less likely to escape through tiny holes or cracks in the tire.

In addition, nitrogen tires tend to stay cooler than regular tires, which can help to prevent flats caused by overheating. As a result, nitrogen tires can be a good choice for those who want to reduce the risk of flats.

Does nitrogen in tires really make a difference?

The short answer is that yes, nitrogen can be beneficial for tires. Nitrogen is an inert gas, which means it doesn’t break down or react with other materials.

As a result, it can help to prevent tire degradation and extend the lifespan of tires. Additionally, nitrogen can help to improve tire pressure stability, which can lead to better fuel economy and enhanced vehicle handling.

However, it’s important to keep in mind that nitrogen-filled tires are not a magic bullet. They will not prevent all tire problems, and they need to be properly maintained just like any other tire.

Additionally, the benefits of nitrogen may not be noticeable on all vehicles. Ultimately, whether or not to use nitrogen in your tires is a personal decision that should be based on your specific needs and driving habits.

Final thoughts

So can you put air in a nitrogen tire? Yes, while it is possible to put air in a nitrogen tire, it is not recommended. The reason for this is that the oxygen levels in the air are higher than those in nitrogen, and over time, this can cause the rubber on the tire to break down.

Nitrogen tires do have some benefits over traditional air-filled tires, but they also come with a higher price tag.

If you’re looking for an alternative to traditional tires, there are other options available that may be a better fit for your needs.
