Nitrogen

This is what I found on the internet.

Why Nitrogen Is Better Than Air. There are multiple reasons why nitrogen is preferable to air in automobile tires: better pressure retention leading to increased fuel economy and improved tire lifespan. cooler running temperatures accompanied by less pressure fluctuation with temperature change. less tendency toward wheel rot.

Do you think I should have my camper tires purged of air and replaced with Nitrogen. Better preasure retention, increased fuel economy, cooler running.

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts ofothergases.


The advantages of nitrogen will be evident in a Formula One racing car, but of little to no value for a trailer.

Consumer reports and the NHTSA did tests and said you can get all the benefits of Nitrogen by just checking your air pressure and topping up every 6 months.

I do that already, so I'm fine skipping the nitrogen-injection.

I had a Nissan Versa Note that came with nitrogen in the tires that I maintained. When I replaced the tires with new Michelins, I used air. I saw absolutely no measurable difference in gas mileage. I saw a bigger difference between winter formulated gas(more ethanol) versus non winter formulated gas(less ethanol).

The main advantage of nitrogen isn't so much that it's 100% nitrogen instead of merely 80%, but that it's dried. Less moisture does mean less fluctuation with temperature, but not by enough to really matter in a trailer tire.

I don't think you'll see noticeably better pressure retention, temperatures, or fuel economy.

Theoretically no oxygen would help keep the tire interior from degrading as quickly.. but it's sort of moot because UV and ozone will kill it from the outside long before the inside's a problem anyways. Might reduce rust on the inside of the rims since it's dry, but again it'll rust from the outside first anyways.

Unless you're racing and really care about that 1-2PSI difference at temperatures generated at a full race pace, nitrogen's a gimmick that provides no real benefit. Doubly so on a trailer.

The main thing we don't want in tires is water. Especially if we are driving at 500 miles an hour, at around 30,000 feet elevation. 60 miles an hour at sea level, it's less of a problem.

So I fill mine with 78% nitrogen.

Hi: Glenn Baglo... The only diff. I found between using pure Nitrogen rather than air is I don't have to drive as fast!!!

I always use a custom blend of 78% nitrogen that the tire dealer gives me a discount on.

I see the above 3 have solved the issue and completely understand my intent.

I have no idea how one might get better mileage from Nitrogen in tires. And it is significantly easier to top off the tire pressure with 78% nitrogen, then 100% nitrogen. I change the tire pressure every time I go from not hooked up, to hooked up for a trip. Every time I carry an unusually heavy load in the truck. And often when when driving on frozen icy roads, vs dry and smooth. Or when on rough dirt roads while crossing the desert. This holds for both the truck and the trailer.

And for those nitrogen advocates, how do you top off your tires when needed? Find a tire shop and pay them?

I simply pull out my air hose and adjust the pressure right at home, if needed. Then, out on the trail, I simply pull out my air compressor and air back up when we get back to black top. On one recent desert adventure, I got three flat tires and a screw in the fourth. All fixed with what we had with us, at least good enough to get home. It had to be done with 78% nitrogen from my comtressor.

100% nitrogen, instead of 78% nitrogen would not allow this unless I carried a nitrogen bottle and had it refilled as needed. Not gonna happen. And there is no way I'm going to get any more moisture in the tires than what is in the air as humidity. That has never been a problem. The only way liquid water is likely to get into a tire is from a water-logged air compressor at a shop somewhere. Unlikely, but possible.

Here is a pic of me plugging one of the flats and one of my tire repair kit.

Any tire shop I’ve ever ask about Nitrogen; always state that it’s a waste of money. PERIOD!

My company sells a tire inflator that generates a high pressure 78% nitrogen gas blend for your tires. Its a steal at only $495 and that includes free shipping.



Of course who is doing the stealing I did not state.. so, has the joke gone on long enough yet?

Upholding?

Hi: Raspy... That tire in your pic isn't flat... it just lacks 100% nitrogen!!!

I also use my custom blend nitrogen mixture first thing in the morning as a quick mental boost to start the day.
I have found that without that each day I tend to .....

It's only flat on the bottom. About 78% full.

Hi: gordon2... I had one of those... but I gave it away. It was full of "Hot air"!!!

Just saw on TV where Nitrogen, OX and Co2 are different weights. Would a mixture of one heavy and one light weight create an out of ballance situation?
