My camper came with tires filled with Nitro air
Can I use regular air to top off the tires if it is under pressure? I just don't know if it is okay to mix two different of air.

If there were such a big difference, dealers would be installing "Nitro" valve stems and "02" valve stems, each with different fittings to avoid co mingling and contaminating the product currently inside the tire.
