As someone who knows quite a bit about reality, I would really like someone to explain the nitrogen in tires thing.
N is 80% of normal air, so what in the world would replacing mostly O with more of it? Do tires have an oxidation problem on the inside?
how would it change milage? if it was H then it might reduce the skin effect and moment of inertia (but i highly doubt this would change much); but N?
All of that bull shit they mention on the sticker is a lie or a serious exaggeration. The reason for nitrogen fill in tires is that it is leas impacted by temperature expansion of the gas. Nitrogen gas in tires is very helpful in places with regular and drastic temp swings so that tire pressure stays more constant. There is also an application for nitrogen in low profile tires and racing tires but a TRX on all terrain 32's would not need that at all.
So 100% nitrogen doesn't follow PV=nRT as closely as 80%?
so i looked it up here (getnitrogen.org) and they say it is water and oil in normal compressed air. they also claim that O will pass through the tire easier than N. The water can condense or evaporate based on temp.
so the tldr on the whole thing is that you should put dry air in your tires, and charge $500 per vehicle for it.
SO that 50$ dryer and the 40$ trap on my compressor line are worth 500$ tire fills?
Nitrogen doesn't expand and contract like regular air. For every 10 degrees of temperature change in the air or on the tires themselves, the tire psi will change by 1. Cold it goes down, hot it goes up.
With nitrogen it doesn't do that as much. Also tires can lose pressure over time through seepage when filled with regular air. The manufacturers say up to 5 psi a month, but that number is extreme. Nitrogen won't do this as much.
Overall it's a scam for people who don't know shit about cars.the tire needs to be purged of all air before adding the nitrogen. Should you need to add pressure to a tire afterwards, better go and try to find a nitrogen fill in the fly, because if you add regular air, you have to start all over again.
Meanwhile, the guys at the dealership rub their nipples as they see you drive away.

Air from a 150psi pump and nitrogen seem the same, dry air must be under one of these, but there isn't a difference.
The difference is from water in the air from what i can see, n2 and o2 are diatomic molecules, and iirc statistical mechanics would say that it wouldn't be until the 3rd term there would be differences in pressure.
as far as leaking through the tire, i can believe that one.
So moral of the story don't be a lazy fuck check your tire pressure weekly fill with air avoid jew fees.
