Anyone running this in there tires?

My boss has just ordered some for his race car and im thinking of using some when I put my new wheels and tires on

It's complete snake oil, unless you're regularly getting your tyres up to 80C tread temperature. It makes sense on a racing car, but not for road cars.

The chief 'snake oil saleman' in the US is Jay Leno and he is now pushing this as a green option for standard cars (after failing to convince folks of the other 'benefits').

My GTR has a nitrogen fill. Most of the benefits are marginal (leakage, upsprung weight, etc). The one advantage is the dryness of the fill.

A former colleage of mine who also has a GTR pretty much proved that by making his own very dry air (he's an industrial chemist).

With a cold fill showing 200 on the TPS he saw the following after really giving it the beans on a route he knows well.

240 on N2

263 on standard air

249 on his dry air

Nitrogen won't do any harm, so if it's free then why not.

Yes, my local tyre place uses it as standard but it isn't 100% nitrogen. It is reduced oxygen air which is >95% nitrogen.

I cannot feel any difference but it supposed to stop oxidation to the inside of the tyres and wheels. Does hold the pressure longer as I think the oxygen in the air reacts inside the tyre reducing the pressure.

Yes I agreed with the positive replies, one issue I do have, as stated above, is that my tyre place (COSTCO) do tend to hold this in lowish pressure tanks, I would have thought if anyone calls it nitrogen and uses good reasons for using it like "dryness" etc, then I'd expect it to get supplied by someone like BOC in high pressure cylinders and it would get called OFN - even packaged like that it should be as cheap as chips as its nothing fancy like some mixes are. One silly comment from me is that I don't like the GREEN valve caps that "it" comes with - so I always change them back to some good looking black ones - oh, and as my daughter discovered naughty little school boys do trade them - so don't park near primary schools if your car is fitted with them!

Atmosphere is made up of about 80% nitrogen anyhow.

If I remember my school lessons correctly, air is 78% Nitrogen, 21% Oxygen, and the remaining 1% is the other gasses.

Yup, most "oxygen monitoring" systems start to warn at 20% - well for occupied areas anyway.

I would think that the main issue for rough workshop generated compressed air would be compressor oil and water, though there are ways to minimise this - which is okay if its been added to the system and it gets regular maintenance.

Liquid Nitrogen would be pretty sweet.

Those are some cool wheels man!

Very cool, go touch them!

what about all the oxygen and UV light on the outside of the tyre then - when the tyre is old all the cracks appear on the outside dont they.

... Most of the benefits are marginal ... upsprung weight, etc...

I dont know what the internal volume of a tyre is, but say you put 50L of nitrogen instead of air at 60psi into each of 4 tyres (total of 800L) you would only save 28g (about the weight of 4 £1 coins in your pocket ) - so yes very marginal

Yep, oxygen leaks out your tyre through the rubber, nitrogen stays in. Next time you fill it you have more nitrogen in there than the atmosphere anyways.

I know that you are only joking, but if your tyres were sealed and that means no possibility of gas passing through the casing,and if there was liquid nitrogen in there, it would be at ambient temperature and only very cold where it was being allowed to expand to ambient temperature - which means if you ended up with a leak then that area of the tyre would end up getting seriously cold and break up as it would stop being flexible. In theory, if you where wearing protective gloves and handling liquid nitrogen and were silly enough to end up with some in the gloves, the advice is not to take the gloves off as bits of your fingers could end up staying in the glove - and that would be a nuisance!
