Can You Add Air To Nitrogen Filled Tires

Can You Add Air to Nitrogen-Filled Tires?

Yes, you can add air to nitrogen-filled tires, but it's generally not recommended to mix the two unless absolutely necessary. This article explores why nitrogen is used in tires, the implications of mixing air and nitrogen, and best practices for maintaining tire pressure regardless of the inflating gas. This is a key consideration for drivers looking to maximize tire lifespan and fuel efficiency.

While nitrogen boasts several advantages over regular compressed air, it's crucial to understand the nuances of mixing the two gases. Let's delve into the specifics.

Why Use Nitrogen in Tires?

Nitrogen boasts several advantages over standard compressed air, particularly in maintaining consistent tire pressure. Here's a breakdown:

• Reduced Pressure Fluctuation: Nitrogen molecules are larger than oxygen molecules, leading to slower leakage rates. This results in more consistent tire pressure over time, reducing the need for frequent inflation checks.
• Improved Fuel Efficiency: Maintaining optimal tire pressure contributes to better fuel economy. Consistent pressure, aided by nitrogen, helps optimize tire contact with the road, minimizing rolling resistance and maximizing fuel efficiency.
• Reduced Oxidation and Corrosion: Nitrogen is a dry gas and contains less moisture than compressed air. Reduced moisture content mitigates internal corrosion and oxidation of tire components, potentially extending tire lifespan.
• Cooler Running Tires: Reduced oxidation translates to lower tire operating temperatures, further enhancing tire longevity and safety.

The Implications of Mixing Air and Nitrogen

While you can add regular air to nitrogen-filled tires, doing so dilutes the nitrogen's benefits. The more air you add, the less effective the nitrogen becomes. This is especially true for the decreased pressure fluctuation benefit. It won't cause immediate damage, but over time you'll lose some advantages of nitrogen filling.

Think of it like this: it's like adding water to a glass of wine. While you can still drink it, the taste is compromised. Similarly, adding air to nitrogen reduces the positive effects of the pure nitrogen filling.

Best Practices for Tire Inflation

Regardless of whether your tires are filled with nitrogen or air, adhering to these best practices will ensure optimal tire performance and safety:

• Regular Pressure Checks: Regularly check your tire pressure, at least once a month, or before long trips. Using a reliable gauge is crucial for accuracy.
• Maintain Recommended Pressure: Always inflate your tires to the pressure recommended by the vehicle manufacturer. This information can usually be found on a sticker located on the driver's side doorjamb or in your owner's manual. Don't rely on the pressure molded into the tire sidewall; that's the maximum pressure rating, not the recommended operating pressure.
• Use a Quality Tire Gauge: Invest in a high-quality tire pressure gauge for accurate readings.
• Address Leaks Promptly: If you notice a consistent drop in tire pressure, locate and repair any leaks promptly.

In Conclusion

Adding air to nitrogen-filled tires is possible, but it's best to avoid mixing the two gases to maintain the benefits of nitrogen inflation. Prioritize regular pressure checks and maintaining the recommended tire pressure, regardless of the inflation gas used. By focusing on these tire maintenance basics, you can maximize tire life, improve fuel efficiency and enhance driving safety.
