I fill my vehicles tires with helium. Makes them lighter. That more than doubles my MPG.
Caution, overfilling with Helium will tend to make the vehicle leave the road

Yes, ordinary air is mostly nitrogen anyway!Apr 24, 2023 07:57:56 #

The only reason to use Nitrogen in tires is because it contains no moisture , and the tire pressure will remain more stable as heat builds, usually when driven at high speeds 100mph or higher.ie. Racing!!!

How about helium? If the car is lighter, it will get better mileage. 🤣 I can see that becoming a sales pitch.

I use helium and get better gas mileage because the car is lighter.

Thank you, I have been wondering about tire pressure consistency. My Audi came with Nitrogen but I've maintained pressure with my own electric pump. I had not thought about it again until your article...thanks !

The guy who recently retired and sold the tire store where I have my work done told me that it really makes no difference unless you have a high performance racing application for it. The practice of inflating tires with Nitrogen went mainstream when dealers found they could make a decent profit from it. He refused to do that, because he had tested it and found it to make no significant difference in tire life or pressure stability.

There will always be some nitrogen in the tires…I presume that the dealer runs the pressure down to 5 or so before refilling them with pure nitrogen. Presumably…the nitrogen is water vapor free which your standard compressed air is not…but a little water vapor in the tire likely doesn't do anything pressure wise. And since your standard air is 80% nitrogen anyway…this whole idea is just a solution they can charge you money for in search of a problem. I've seen claims on the net that nitrogen escapes less via leaking out through the rubber than air does…but since (a) air is mostly nitrogen and (b) nitrogen and the majority of the other air in tire is oxygen which is almost the same molecular weight and hence doesn't escape appreciably faster or slower than nitrogen…that seems like a pretty bogus claim to me.

Interesting about the nitrogen, the military uses nitrogen filled tires on their aircraft especially for carrier ops. It seems that nitrogen filled tires will not skid on the carrier deck. On another note I recently had to add air to a tire while on my way to work, the closet place was a costco and when I pulled up to the dispenser I read it and it said that it puts out nitrogen to fill the tires, you set the pressure for the tire and the inflation valve locks onto the valve stem. Keep in mind that this is for costco members.

Ok all you smart guys. Is the issue not the amount of water vapor in the air mixture; not because water vapor reacts differently than nitrogen or oxygen gas, but if the temperature drops to a certain point, that water vapor will become liquid water. Hence less gas in the tire; hence less pressure and more tire wear. Please respond to this logic.

No one cares. It's all marketing BS designed to part you from your money. Why this is even a thread is puzzling. It's likely to go on for 20 pages, though.
