Anyone here tried using Nitrogen for you tyres? Eversince I read some articles online about this stuff it really made me wonder what's the difference. I read here some so called "the facts, the half-truths and the lies" - https://practicalmotorin...res-definitive-answer/. While this article said that using nitrogen can also help to save - https://www.tyroola.com....ear-just-on-your-tyres/
Anyone here have insights and opinions about this?

IMHO most it is BS & marketing hype.
In my experience the pressure drop in tyres on ordinary daily drivers, doesn't appear to be much slower with pure nitrogen versus plain air. I have several friends using nitrogen in their tyres & this seems a common comment. Also this thing about nitrogen molecules being larger therefore are less prone to leaking thru the tyre walls sounds a bit iffy, especially when you consider that plain air is 80% nitrogen anyway.
It's main advantage is that it's dry, i.e. contains no water vapour. This means that there will be less variation in pressure between cold & hot, leading to better tyre wear control. Great for race cars, but on everyday drivers ?
Also, the lower water content supposedly leads to longer rubber life internally. How long to tyres last now, using plain air ? I don't know of too many which have been replaced because of deterioration of the rubber internally. They usually wear out first.
I think it has perhaps more application for military vehicles & planes. Tyres fitted to planes have used pure nitrogen for decades. Can you image the problem with water freezing inside the tyres at high altitude ?

Dr Terry Hey Dr. Terry, Awesome insights! I guess, everyday drivers are not actually aware of this, or even so, they might just use the same and usual air for their tyres. Like me, I still stick to pure air, that's why I was quite curious about Nitrogen's performance when used in Tyres. Yeah, you have a point, Planes should really use Nitrogen. "water freezing inside the tyres at high altitude" - That would be troublesome.

I think I will go for the green option of filling tyres with any politically correct harmful toxic gas, that way we will save the planet.
