Nitrogen Tire Refill

 How Do I Know if My Hyundai Tires Contain Nitrogen?

If you bought your tires with nitrogen already in them or had them filled purposely with nitrogen somewhere, there’s a good chance the air caps were changed to indicate it. If they’re green in color or have “N2” written anywhere, they were filled with nitrogen. Likewise, if you recently purchased your Hyundai, you can always call the dealership and ask.

 How Nitrogen Makes a Difference

More drivers are switching over to nitrogen in their tires for a few reasons. The first is that nitrogen molecules are larger than regular air, so they tend to leak out from tires at a slower rate. This means less frequent air fills for you and can be both a time and money-saver. It’s also worth noting that tires with low air pressure can weaken your fuel economy and cause you to have to fill up on gas more. Slower-leaking nitrogen may very well increase the amount of mileage you get on each tank. Finally, nitrogen-filled tires have been shown to result in better performance, their more stable pressure providing better grip.

 Can You Mix Regular Air and Nitrogen?

The short answer is, yes, you can top off regular air tires with nitrogen and vice versa. However, it is recommended that you do not do that and go with entirely one or the other. It’s fairly difficult to ensure an even mixture of nitrogen and regular air molecules across all four tires, which can lead to alignment and performance issues. Furthermore, your tires’ warranty (not to mention their longevity and performance) may be affected if you fill them with an air blend they are not designed for.
