Nitrogen inflation to 125psi

[SurfOgre]

So, got our Solitude 310GK a few months ago and the tires are supposed to be at 125psi cold. They are also currently filled with nitrogen. They are about 15psi low right now, but I cannot find anyone in the San Diego area that can top them off with nitrogen. I can get them to 125psi with air and am not a rigid advocate of nitrogen, but would like to keep them inflated with nitrogen if possible. Have called RV dealers, semitruck shops, and tire stores with no luck. Anyone know of a place in the San Diego area than can provide nitrogen to 125psi? Thanks.

Try a welding supply shop.

Every compressor in the world provides 78% nitrogen gas. The whole nitrogen inflation thing is just a silly scam.

That doesn't take away from wanting dry nitrogen.

The tire oxidizes, absorbing the oxygen, leaving only the nitrogen. If the stories about nitrogen were true . . . how would a tire filled with nitrogen lose pressure? (which they always do). Just air up your tires with any compressor.

... or dry air from any portable compressor. I suspect the Owner's Manual only references adding air to correct loading pressure and ne'er a mention of nitrogen. If finding N2 is tough at ground zero, imagine trying to find it on the road. Not something that keeps me up at night.

NoPeeking true enough. It's the dry characteristic that counts. Not many portable compressors or service station compressors have desiccant dryers.

SurfOgre, you probably already know from owning previous RVs that you'll be spending some time adjusting tire pressure due to absorption of the gas by the rubber, elevation changes, and other reasons. Honestly, unless you plan to travel with your own nitrogen tank, you'll end up using a common portable air compressor.

I too went down the Nitrogen rabbit hole. Just had to have it. Well, until I couldn't find it. Sure local tire stores could fill auto tires all day long to 40psi with it, but none of their equipment would get to 110PSI, my tires at the time.

So I read and read about nitrogen, how it really does effect tire longevity.. What I found was that water in the compressors actually is what causes premature tire failure. The thing about using pure nitrogen is that there is no water vapor.. So I looked at buying nitrogen filling equipment, whoa baby, theres a buck or two involved. At the time I was using my old scuba tank as a tire filling air tank. The upside was the air put into scuba tanks is stripped of moisture. Yea! the bad news it's pretty expensive to maintain dive tanks if you are not using them often. At the time $20 to fill, annual inspection $69, 5 years hydro inspection $130. But I forgot to get the hydro done, so a couple hundred to get it recertified and filled. So I bagged it.

I bought a California Equipment Compressor. It's not the best option out there, but it pump fresh air on each fill, so I get ambient moisture, but not collected (condensated) moisture. The good news is I wear my tires out using them long before the internal moisture has a chance to break the rubber down.

There are no "right" answers, only decision that must be made.

I've always figured that 78% to 79% nitrogen is about perfect.....

In Texas, most of the Costcos have nitrogen tire inflation stations outside the tire departments - but doubt you could get an rv in the busy Costco parking lot.

I understand you wish for Nitrogen, but as mentioned air is 78% Nitrogen anyway. I am lucky to live in the west so there is very little moisture in compressed air here. Discount tire has this article https://www.discounttire.com/learn/air-vs-nitrogen.

Now many years ago I was also intrigued as my GD dealer said I had to use nitrogen - they had a filling station but for $$$$. I quickly learned it was a sales gimmick.

Now having said that I think over at iRV2 years ago was a thread where someone connected a small nitrogen welding tank through a regulator and use that to inflate, but it was pricey Good luck

Thanks, all. Looks like the very small (and questionable) benefit is far outweighed by the difficulty and cost of keeping them filled with nitrogen. Will fill with conventional means. Appreciate the guidance.

OK, I'm going to open the rabbit hole. If moisture is the main problem, why not put one of these https://www.amazon.com/LEMATEC-ZN312...86&sr=8-6&th=1 on your tire fill inflator? The ones I use for closed space moisture control are rechargeable (I use the microwave on defrost). Just let them cool completely before putting them back in. I have even put them in Vacuum bags to keep them dry.

Okay, I'll play... I've been air-filling bike, trailer, lawnmower, car, truck, etc. tires for 50yrs and never had a moisture-related issue. Am I the lucky one? Or, just didn't know I had a moisture issue? I get it for industrial/commercial applications for critical equipment where moisture in air needs to be controlled, but for a trailer tire???
