Nitrogen instead of air in tires
I replaced the tires on our coach and it was recommended that I fill them with nitrogen. They said it would improve mileage, improve tire life, and the pressure would be constant.
I didn't do it, but a friend of mine just did and started me wondering if I made the correct choice.
Anyone have experience with nitrogen filled tires?

I think it's great, just to much of a pain in the a!! and cost, sure it's better. Good old air is fine with me.

With a degree in Chemistry, I believe it is a crock.

I use a special proprietary blend of 78% Nitrogen, 20% Oxygen, and 2% trace elements. It works pretty well for me.

Years ago, when I was very young, my dad owned a Mobil filling station in Loveland CO. When they use too pump the gas, and wash the windshields. Always had high school kids working there. In the summer, we had lots and lots of tourists. And some cars had canvas water bags on the front for overheating in the mountains.
One of the enterprising kids came up with the scam for these out of state customers: they needed, new thin mountain air in their tires, since they had flat land air from a lower altitude. And for a buck he would take care of all four tires.
Dad put a stop to it, but before he found out there were some gullible people who had paid.
I think nitrogen for tires falls in the same category

Ordinary free air is 78.09% nitrogen.

Oxygen permeates through small passageways (rubber) faster than Nitrogen. For our applications, I do not think the difference is meaningful.
More impactful, IMHO, is that compressed air is saturated with water vapor which will condense and vaporize in the tire during temperature cycling, causing possible corrosion on steel rims, and creating pressure fluctuations.
Here is a technical article of O2 permeation as compared to N2 permeation. Not promoting N2, just providing some info.
There are benefits of N2 filled tires in some applications, where 1 psi fluctuation makes a difference in performance (ie Nascar) or large temp fluctuations, or safety concerns (airline tires).
My thoughts,
Brian

Ask if you get your cash back, if you get no improvement on mileage.
That way it will be free.
Also ask what % of improvement in MPG there should be.

Cars that run 200MPH have nitrogen in their tires because constant pressure if very important at that level. Our vehicles gain nothing by it.

I have a friend who told a lady co-worker that she needed to change the air in her tires twice each year (winter & summer). That night, she told her husband to get her new air for the summer. He laughed until he cried. She confronted my friend the next day & gave him hell!

Gotta jump in here- as this subject comes up about every year.
I have Nitrogen in All of my tires, Cars, Truck , MH- and Race Car, Race Trailer.
Simple Reason ---- Pressure never varies in -10 to 80's when I head to Florida in Feb from Indiana. I carry a 30 size tank and reg on board just in case.
There are Pro's and cons to Nitrogen in tires, I think the Pro's out way the Con's.
It's just personal preference I like knowing that my 22.5's are the same all Day long.

I'd love it if someone could explain to me how nitrogen is supposed to be able to ignore all the laws of physics! It's impossible for a given volume of a gas (any gas) to remain at the same pressure when its temperature changes. I've been hearing this nonsense since tire shops started using nitrogen, and I'm amazed how many people fall for it!
There are advantages to using nitrogen, (the lack of water vapor has already been mentioned) but it does NOT magically adjust its pressure as the temperature changes.

Not disagreeing with your last sentence, but that's the exact reason why plain air pressures vary - Moisture, The lack of moisture the more stable the pressures remain , Hence why I use Nitrogen.and I can attest to the fact that my pressures don't swing. I don't think it's nonsense- Just personal preference.

Nitrogen has benefits in tires used for air craft or race cars.
For a vehicle at normal speeds, it serves no practical purpose.It is a profit center for the tire seller.
If it makes you feel better, spend the money on it.It won’t hurt, but remember that it is not as easy to find 100% Nitrogen for bring tires up to pressure.
Normal air contains 78% Nitrogen, so is it worth it for an extra 22%?I think not.
The next time I tow my trailer at 200 MPH or it has the name “Boeing” on it, I will use nitrogen.
