My camper came with tires filled with Nitro 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.
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.

All of my vehicles have nitrogen in them as that is what Costco put in them when I purchased the tires. And all have a TPMS system to monitor air pressure. In cold weather the pressures are 2-3lbs lower in the morning then in warmer weather. I may be able to run all summer without adding air as you have stated but as soon as the temperature drops I see a change in pressures. But since I am not towing in the winter a few lbs. lower pressure isn't critical. My point is that nitrogen filled tires are also effected by temperature. But I do believe that they hold pressures better over a period of time and I don't have to add air as often.

Yes you are right, you will see a couple pounds difference which isn't anything to worry about but with normal air in the tires you can see a 5 to 10 pound drop. Just this morning after commenting on this thread I jumped in a rig that had 70 pounds in the tires Tuesday when I drove it and today the TPMS is flashing telling me that I now have 62 pounds in the tires. Why the change, well the temp dropped yesterday.
