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.

While away from home, I noticed that my car tires with Nitrogen were low. Pulled into a busy tire store, they topped each tire with Nitrogen, no charge. Don't get too hyped up about it, the air you breath is about 85% nitrogen.
