Nitrogen filled tires

[stevensmith2859]

When my wife and I did are walkthrough on our 2015 28DBUD last spring, the technician actually told us they fill them with nitrogen, but is a ploy, he said just use air, don't pay for nitrogen if they need it.

I don't care what anyone says I like the green caps! lol

If it provides you with a tad bit more "peace of mind" then it is money well spent.

I'll keep my cheap black caps and use the money we save to take the DW to dinner.......a couple times

I would lose green ones in the grass! Black looks like a bug so I can find those!

We use OTR air.

I guess I will add my opinion to the mix. I have a FR3 28DS. I use shop air in my tires. I also own a TBM 700 aircraft, a single engine turbo prop. I regularly fly at 28,000 feet. I am required to use nitrogen in the tires. Not for stability, not for pressure consistency, not for temperature differences. The reason is fire protection. Nitrogen is an inert gas. So if the brake caliper catches fire and pops the tire it will not feed the flames. Same in any aircraft from a 747 to a Cessna.

Cars, trucks etc - nitrogen is a gimmick, add on after sale way of extracting $ from people. If you want dry air use a coalescing filter on your compressed air. Checking your pressures weekly will do more for you and your expensive tires than using nitrogen will. I check my tire pressures before every flight, you should too.

Ok, not being smart... But then why not use air.. It is also inert..

Dry Nitrogen is great for aircraft tires and pitot static system purging. It is also great for Keurig K-Cups. Dry Nitrogen will not support fire.This debate seems to come around every year and it always comes down to everyone has an opinion (me too) and everyone sticks to their guns. Let it go Louie, let it go.

I would be remiss if I didn't disagree with you. It is not about being smart, I am confident you are very intelligent. Air that we breath is made up of a large percentage of nitrogen, smaller percentage of oxygen and fractional percentages of other gasses. Your statement is somewhat correct with the exception of that oxygen is a catalyst that will support combustion. Pure oxygen (above 90 percent) will auto ignite (oxydize) in the presence of oil. Nitrogen is inert in the fact it will not support combustion. It is has been used as a fire suppressant. This is why it is used in aircraft tires.

So your cars engine uses the same air you breath to support combustion in each chamber. Without it the fuel will not change state. If you used pure nitrogen and introduced it into your cars intake system it would not start or run.

Agree with AD, O2 is not inert and the issue is fire safety in aircraft tires, not a travel trailers. Over the pressure and temperature ranges involved, Nitrogen reacts to pressure and temperature almost exactly the same as dry air. Some aircraft tires, depending on the aircraft, can have over 225 psi tire pressure. In a retractable gear aircraft the tire is sitting right up again a tank of combustible jet fuel or Avg gas. A tire exploding could have catastrophic consequences as you can imagine. N2 would have more of an extinguishing effect. Air could cause an explosion easier.

It's also cheaper to use N2 in aircraft because most air compressors are only good for about 125 psi. Airport N2 usually comes in cylinders with very high pressures. A cart with N2 is easier to move around the tarmac, not flammable and moisture isn't an issue. It's more expensive to filter compressed air to the higher pressures. Moisture is not an issue in the production of N2.

But also mentioned, for a travel trailer, non of this matters.

Several times a year....monthly it seems at times

This all come down to each what individual likes or wants, it's up to each of us. I like nitrogen in my tires, right now I am going to keep using what I have now which is just regular air. This just comes down to what you like. I don't like MacDonalds but I am willing to eat at Ruby Tuesday and pay $10.00 for a hamburger that I could buy from MacDonalds off the dollar menu. This is my choice same as nitrogen, just what I choose to do.

Agree, it certainly won't hurt and has some benefits.

Yep! X2

I am also a pilot of transport category as well as General Aviation airplanes. I prefer nitrogen, but I generally buy my passenger vehicle tires at Costco - so nitrogen is provided there. I also have a nitrogen tank at home that I use for top offs and the airplane tires - even though my airplane is not subjected to really low temps.

I think the lack of oxygen in the dry nitrogen is also helpful in reducing oxidation on the inside of the tire - which you cannot see.

Overall, one has to decide if the incremental cost and difficulty in getting nitrogen on the road is worthwhile. I use it on all my cars and trucks, but haven't decided to do so on my RV.

Just another opinion worth what you paid for it.

I believe that compressed air doesn't fall under the category of Inert. It contains oxygen which is one part of the fire triangle.

[doc73]

You would be correct, I was just stumped how a split second of a tire failure (before all the air dissipates into, well, the air) would make a worse fire. So, no it is inert but it is also not going to burst into flames (otherwise we'd be screwed on earth) . I could see how maybe the N2 would extinguish the flames, maybe.. Still think a bursting N2 tire under a fuel tank would such as much as the air. But I see the point about the fire as AD2 put it. When I read the post I was simply thinking a tire on the ground on fire or similar not in an enclosed space.
