Tire Pressure

I just purchased a Flagstaff VLite with Nitrogen filled tires. When I checked the tire pressure it was 40lbs in all 4 tires. The sticker on the trailer says the cold tire pressure is 50lbs. I checked them in the morning around 9:00AM and the outside temp was 50 degrees. I
don't have any experience with Nitrogen filled tires. Would the above indicate that all 4 tires are low?? Any thoughts are appreciated.

Many Thanks...

I have always been under the impression that yes... They are low. Air and Nitro are treated the same.

Buy or borrow an air compressor and fill them up. The sooner the better.

The nitro is mostly a sales gimmick. Air your tires up in the AM to the max tire pressure, regardless of the ambient temp, and be done with it till the next day.

Can you mix standard air / Nitrogen or should it be topped off with Nitrogen?

The air we breathe is 78% nitrogen, so no, the tires don't have to be topped with straight nitrogen.

Tire pressure is too difficult for some dealers to understand. My truck had low pressure as did my trailer when new. Both are Nitrogen filled, or were. They are now at the proper pressure and checked regularly because I do it, not a dealer. I asked why the tires were low and got a blank stare. I was told by both dealers that tires are filled at the factory with Nitrogen and should be fine.....duh! I always check to make sure service is done because too many times is isn't.

The TRA & RMA both say a tire being operated at 20% below recommended cold tire inflation pressure is in a "run flat" condition. Tires operated for any length of time in that condition should be removed from the rim and inspected for signs of internal failure.

So, you must ponder the fact that they may have came from the factory like that. Another clue is the fact that the maximum bead seating pressure was 40 PSI.
