Nitrogen infllation of tyres?

I have to admit that we nitrogn fill tyres where I work as well.

partly because the only thing we have that can deliver the 175 PSI thats needed is either the oxy bottles, the mig gas regulator OR the nitrogen charge system that we use for filling hydraulic accumulators.

Hey Scarry,
The deflation would be a lot funnier with helium.......... Plus being helium would make the car load on the road surface less being lighter, you might hit a speed bump and travel further than you expected........

Hi Dave, a little off topic but we run 200psi LP compressors all the time!! In fact there is one in every system we build not to mention that there is always the use of HP compressors which could give you up to 5000psi.
However try filling the tyres straight from the oxy bottle on your oxy/acetylene set, should be good for a few laughs:D Probably should do that on a custom you don't really like that much:wasntme:

we use nitrogen for club racing tyres mainly as they increase pressure less when they get hot, but on 4wd id say its overkill unless for competition use ie Finke desert race ect

I guess if the above is true it is pointless if I change tyre pressures when off road.
comments?

Was told by a proprietor of a tyre store who used to supply tyres for the "Australian Touring Cars".
In racing, where tyre inflation is critical, to know what pressure your tyre is at what temperature is vital. They use nitrogen.
Air is, what, about 80% nitrogen anyway.
If you're not racing on a circuit, to fill your tyres with nitrogen only, a pointless waste of money. Especially if you're going to be airing down.

we dont have one of those compressors and purchasing one just to do one varient of vehicles tyres?

I have thought about suggesting we get a set of dive tanks converted so that we can use the dive clubs compressor.

When I was using bottled air in the race car I made an adapter and had them filled at the local dive shop. (much cheaper than my bottled nitrogen ;))
It was dry enough not to notice any difference between my dry nitrogen and we always ran our tyres to a hot pressure anyway.
