Just wondered if anyone has any experience of this? I know it's used in racing and is considered more stable than normal air but I was interested in the idea of it losing less pressure. Have read you'll likely lose 1psi a month with normal air and with Nitrogen inflated tyres it's 1psi every 5-6 months. Local place to me does it for £1.25 per tyre so not exactly an extravagant option but wondered on people's thoughts.
I remember watching a 5th gear episode where they tried out the nitrogen tyre filling. From what i remember it was a waste of money, much less stable than normal air with heat etc(more pressure variance) and same for losing pressure i'd imagine. Think it said fine in racing etc as they ensure its just nitrogen, but in normal tyre places the "nitrogen" had more water vapour etc in it than normal air making it worse!
Hmm well that's not much cop as the whole point is less water vapour. Intrigued by it, if it was done properly.
Nitrogen will expand and contract just the same as normal air, it's just that the molecules are bigger so less will escape and holds pressure for longer than air alone.
Not correct , look at he termal coeficint of an air and nitrogen. Nitrogen is more than 10time more innert to heat than other gases found in regullar air. I hat it and when cheking the pressure after heavy riding or motorway use the presurr didn't changed a bit. Also nitrogen will heat up it self much les than regular air. The problem is when you get pour quality nitrogen is more water in it than in sea so it will expand more. But that is same if bad compessor is used and the tank holding the ait isn't dry etc etc...
Had it in mine last couple of tyre changes, no different really, still check and have to adjust the pressures every few weeks
I work with aircraft and we use nitrogen to inflate the tyres, and the pressure always increases due to the heat generated on landing etc so I was basing my experience on that. I've not really tested it on a car, and granted an aircraft generates a bit more heat than a car so that may be why
