Nitrogen-filled tires have gained popularity in recent years due to their potential benefits, such as improved tire longevity, reduced pressure fluctuations, and enhanced fuel efficiency. However, a common question arises: can you put air in nitrogen-filled tires? Understanding the answer to this question is crucial for maintaining optimal tire performance and safety.

Can You Put Air in Nitrogen-Filled Tires?
The short answer is yes, you can put regular air in nitrogen-filled tires. However, it’s generally not recommended for several reasons.
Why Nitrogen is Used in Tires
Nitrogen vs. Regular Air
Nitrogen makes up about 78% of the air we breathe, while oxygen comprises the remaining 21%. Regular air contains both nitrogen and oxygen. Oxygen is highly reactive and can accelerate tire aging by oxidizing the rubber compounds. Nitrogen, being inert, does not react with rubber, thus slowing down the oxidation process and extending tire life.
Furthermore, nitrogen molecules are larger than oxygen molecules, leading to less permeation through the tire walls. This results in more stable tire pressure, reducing the need for frequent adjustments.
Nitrogen-filled tires have gained popularity in recent years due to their purported benefits, such as improved fuel efficiency, longer tire life, and reduced maintenance. However, a common question arises: Can you put air in nitrogen-filled tires? The answer is a bit more nuanced than a simple yes or no.
Understanding Nitrogen-Filled Tires
Nitrogen is a colorless, odorless gas that makes up roughly 78% of the Earth’s atmosphere. Unlike regular air, which is a mixture of nitrogen, oxygen, and other trace gases, nitrogen-filled tires contain a higher concentration of pure nitrogen. This difference in composition leads to the claimed benefits of nitrogen-filled tires. (See Also: Is 40 Too Much Air In Tires)
Benefits of Nitrogen-Filled Tires
- Improved Fuel Efficiency: Nitrogen’s lower rate of diffusion compared to oxygen can help maintain tire pressure more consistently, reducing rolling resistance and potentially improving fuel economy.
- Longer Tire Life: Consistent tire pressure can also help prevent uneven wear and tear, potentially extending the lifespan of your tires.
- Reduced Maintenance: Nitrogen-filled tires may require less frequent pressure checks due to the slower rate of pressure loss.
- Better Ride Comfort: Maintaining optimal tire pressure can contribute to a smoother and more comfortable ride.
Can You Put Air in Nitrogen-Filled Tires?
Technically, you can add regular air to nitrogen-filled tires. However, it’s not ideal and can diminish the benefits of nitrogen.
Why Adding Air Isn’t Ideal
When you add regular air to nitrogen-filled tires, you’re essentially introducing oxygen back into the system. Oxygen is more reactive than nitrogen and can contribute to:
- Faster Pressure Loss: Oxygen molecules are smaller and diffuse through tire walls more readily than nitrogen molecules.
- Increased Corrosion: Oxygen can react with the metals in your tire and wheel, leading to corrosion over time.
- Uneven Tire Wear: Pressure fluctuations caused by oxygen diffusion can contribute to uneven tire wear.
What to Do If You Need to Add Air to Nitrogen-Filled Tires
If you find yourself needing to add air to your nitrogen-filled tires, it’s best to:
- Visit a Tire Shop: Most tire shops have nitrogen inflation equipment and can safely replenish your tires with nitrogen.
- Use a Nitrogen-Specific Air Compressor: If you have a nitrogen-specific air compressor at home, you can use it to add nitrogen to your tires. However, ensure that the compressor is properly calibrated and maintained.
Avoid using regular air compressors to add air to nitrogen-filled tires, as this can introduce moisture and contaminants into the system.
Recap
Nitrogen-filled tires offer potential benefits such as improved fuel efficiency, longer tire life, and reduced maintenance. While you can technically add regular air to nitrogen-filled tires, it’s not recommended as it can negate the advantages of nitrogen. (See Also: Why Are My Tires Screeching When I Turn)
If you need to add air to your nitrogen-filled tires, it’s best to visit a tire shop or use a nitrogen-specific air compressor to ensure the integrity of the nitrogen-filled system.
Frequently Asked Questions: Nitrogen Filled Tires
Can I add regular air to my nitrogen-filled tires?
Yes, you can add regular air to nitrogen-filled tires in an emergency. However, it’s not ideal as it will reduce the nitrogen concentration and affect the tire’s performance. It’s best to top up your nitrogen levels at a service station equipped for nitrogen inflation.
How often should I top up nitrogen in my tires?
Nitrogen levels in tires naturally decrease over time due to diffusion. It’s recommended to top up your nitrogen levels every 1-3 months, or as needed based on your driving habits and tire pressure monitoring system (TPMS) readings.
Will adding air to nitrogen-filled tires ruin them?
Adding regular air to nitrogen-filled tires won’t ruin them, but it will dilute the nitrogen concentration. This can lead to decreased tire longevity, reduced fuel efficiency, and potential performance issues. (See Also: How To Rotate And Balance Tires)
What are the benefits of nitrogen-filled tires?
Nitrogen-filled tires offer several benefits, including improved tire longevity, better fuel efficiency, reduced risk of flat tires, and enhanced handling and ride comfort.
Can I convert my tires to nitrogen myself?
While it’s technically possible to convert your tires to nitrogen yourself, it requires specialized equipment and knowledge. It’s generally recommended to have this done by a professional at a service station equipped for nitrogen inflation.
