Nitrogen filled tyres?

[Manky Monkey]

I was perusing the North Hants Tyres website & came across this. Fill your tyres with Nitrogen for 2 quid per tyre. That's a new one on me. Anyone tried it?

I quote from another forum

"Filling Nitrogen in tyres has NO apparent advantage over normal compressed air! It's a marketing gimmick, ignore it."

But I will look in to this a bit more before I agree or disagree with this statement.

What about filling your tires with helium making your car lighter

It is supposed to keep tyre pressures contant as it isn't affected by the temperature changes we get in the UK on road tyres. Never done it in a vehicle but we used to fill the tyres on a coating plant drying drum with nitrogen due to the heat and it worked on that.

Always been a bit suspect for cars and bikes and stuff especially as air is generally free

Many years ago I filled a front tyre with straw, to replace a shredded tube, to get me home, but I wouldn't recomend it! does nowt for the handling........

So is nitrogen if you know where to get it from xD. I have heard about filling your tyres with nitrogen before, Can't quite remember where though.

The blurb on N.H Tyres' site says Nitrogen slows wear to tyre rubber & keeps tyre pressures constant etc -is it really worth worrying about?!

Maybe if you're someone like McClaren.........  



(08/03/11 following Trev's posting below -  maybe that should be "McLaren"? Show how impressed I am with F1 !!

don,t they put it in the massive dumpers in quarries.

Think we may have ended up doing that just before I got made redundant, was some gas/air mix but can't remember what.

It only reduces tyre wear by keeping constant pressure from what I have seen. If you are one of those people who regularly check and adjust pressures there is less advantage. I know a few raved over it on the car forum I used to belong to but I have never used it outside of a work environment. Thinks its same as owt else, ya pays ya money and tales your chance

Somebody tell me if i`m wrong (I`m sure you all will) my murky memory of chemistry lessons tells me that when Nitrogen is heated it actually cools and liquifies, thus cooling the tyre which then heats up a bit again and so on and so on. This could be the reason for better tyre wear claims. Does that sound right. I will happily stand in the corner with the dunces cap on if I`m wrong.
