Nitrogen /air in tires

If you do have nitrogen in your tires, make sure you rotate it every six months. You can get a nitrogen distribution manifold from Amazon, or build one yourself. Even better, is to replace the nitrogen with pure hydrogen. Hydrogen is lighter than atmospheric air, and will make your towable product much lighter. You can test the hydrogen monthly by depressing the tire valve while holding a match or lighter close to it in order to see if it burns cleanly.


Disclaimer. Don't do what I posted in the above paragraph. To answer your questions, you can certainly mix nitrogen with regular air.
