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.

What amazes me is most guys on this forum all worried about tire pressure and say to check it often but when the use of nitrogen comes up they claim its a waist of money and snake oil.
I'm a fleet manager with over 60 4x4's in my shop, all of them newer with some form of a TPMS system. I have to tell ya every fall as the temp drops each and every one of them trucks will flash a low pressure warning. Of course in years past this has occurred but it wasn't as noticeable as the dang low pressure warning lights that flash at start up on the newer rigs. What brought it home for me was when the wife and I purchased a newer rig with TPMS and as the temps dropped in the fall the wife would call multiple mornings on the way to work saying she had a low tire light, I would tell her its probably due to the 10 degree temp drop over night and I would check them when she got home.
To ease the wife's worry I took my personal rig to the tire shop and had them inflate the tires with nitrogen and as a test I had my work truck tires changed over to nitrogen, this was 3 years ago. Well guess what, no more pressure swings due to increases or decreases in the ambient temp. Sure I might get a pound or two swing but not the 5 to 10 pound swing I was seeing without the nitrogen.
So for guys worried about trailer tire life and the effects low air pressure can have on a trailer tire I would think that nitrogen would be a no brainer. I don't have to worry about heading out to the mountains in the fall when home temp is around 60 degrees and ending up 5+ pounds lower when I get in the 30 degree temps. I have not put air in the tires of the 2 trucks I drive in the last 2 years or the trailer since I purchased it a year and a half ago. I do check trailer tire pressure often just to see if they hold as well as my truck TPMS system tells me my truck is doing and I verify the truck TPMS system with an old fashioned gauge every once in a while.
Regular old fashioned air can be added to a tire filed with nitrogen but its best to get the tire up to pressure with nitrogen as it will stay that way unless there is a leak.
