Forgive me since this is not a boating question & I realise this isnt a car forum but does anybody fill their tires with nitrogen? And if so do you really see any differnece between air/nitrogen? Any negatives at all. Thanks!
the concept is great because nitrogen pressure does not increase with an increase in temperature. The pressure will remain constant, unlike compressed air which will decrease when the temperature is lowered and increase when the temperature is raised. The problem is that it is as available as a Hydrogen fuel cell filling station. Great ideas, just not available to the general public.
If the oxygen permeates through the rubber. Doesn't the percentage of nitrogen increase as it stays in the tire according to them. Each time you top off your tires you are ending up with more nitrogen and less oxygen each time. Sounds like snake oil to me. We used to use it at the race track because it was available, but I don't think I'd go out of my way to obtain it.

Not true. Gaseous nitrogen and air are identical in this regard. For both, in a confined volume like a tire, pressure goes up with rising temperature and it goes down with falling temperature. Google Boyle's Law and check it out.
We used nitrogen in the tires on the race car back in the 80's. It helped a lot in maintaining optimum tire pressure. I have seen this with my own eyes, not some theory.
The key is the high purity compressed nitrogen is a "Dry" gas. VERY low percentage of moisture compared to compressed air. Thus less (Very little) pressure change at different temps. The moisture expanding and contracting with the temp. change is the largest contributor to the pressure change at different temps, barometric change or Elevation change.

I guess all these crazy theories like the Perfect Gas Law and F=MA go out the window based upon you race car experience in the '80's.
We're not talking about moisture in the gas. We're talking about nitrogen vs. air. Given equal moisture content, one has no advantage over the other. It's a scam. You can also get dry air, ya know?
If I am correct that is what the Nascar guys use in their tires. It does not expand and contract like air does and air pressure is very important to them.
Really can not see why anyone would use it in regular use

Moisture free air is about as available as nitrogen refills.
Nitrogen filled tires
