as title states, im just curious really

have you noticed the benifits?


im tempted to try it out

wat are the gains never heard of this before

subaruturbo_18

i heard of it briefly a while ago but got told more about it today when getting a tyre fixed.


the theoretical benifits are that, as nitrogen is lighter, it reduces tyre wear, and improves fuel economy (ever so slightly i would guess) and if the tyres are lighter they may be able to spin just a bit faster but i would guess such a small amount that you wouldnt notice it. The downside is you need to get it topped up once a month ,but only costs a few quid.

Interesting read here: The Straight Dope: Is it better to fill your tires with nitrogen instead of air?

Seems the benefits are limited really; but if it's cheap enough, it can't hurt

I always thought the main benefit was that less of it would escape through the fine holes in rubber, so would need to be topped up even less. Thats was the marketing they were using a few years ago.

The main benefit of nitrogen is that it expands (with heat of course) at a constant rate, air does not.
Thats your benefit.

why pay for sumthing were gains are so small you wont notice wen u can get air for free

subaruturbo_18

the grease monkey at the tyre place diddnt mention that.


might have to give it a try

every little helps apparently they use it in f1 so it must do something

The new Nissan GTR comes with nitrogen in its tyres as standard, or at least it does in Japan...

not worth the hassle

The real benefit with nitrogen, is that the pressure remains the same whether the tyres are hot or cold. Very useful if youre involved in serious motorsport, of no benefit at all if not...

We all have about 78% nitrogen in our tyres

Got Nitogen in all of mine too

Why not when its free - just have to ask.

As said the atmosphere is mostly Nitrogen anyway, bottle stuff lacks the trace elements that make up the rest of the air we breath (CO2, Oxygen and some other tiny amounts of the rest of the gasses from the periodic table and water vapour). It is more stable and tyre pressure will be more consistant as the tyres heat up. Good for a formula 1 car or other extreme sports but I doubt it is not worth it for the road...

If it's free....

free, where from ??

And in the cost-no-object world of motorsport, why not Helium to reduce unsprung weght?

Attention to detail. One small mod might not be noticeable, but apply these everywhere and it will.

The pit crews would have to hold the tyres down, so they didn't float away ... sorry couldn't resist.

Right i have used nitrogen in my tires for a few months now. i am running in new tyres and it does improve admitedly only a slight amount, but yes the gas doesnt expand the tyres so you dont pump them to normall air pressure but to the actual pressure u want to run on. this can take alot of trial and error, the bennifits are worth it as it should be free to fill your tyres with nitrogen, i went to tyre pros and they filled my tires up at no cost, and they adjusted the pressure as i saw fitt. which was great customer service.

StickyMicky

^ you blatantly work for them

I run 78% nitrogen and 21% oxygen: the remaining 1% is a secret mix.....

Ginge !

i remember renton from redline done this once for a track day to help the tyres,,,, he seemed to think that it wasnt worth it though im not 100% why

i can see the reason though,,, tyres stay cooler, keep stable temps meaning that the presures stay consistant rather than lowering the presures to 25psi if a hard wearing track like the ring ( yes i said track ) or 28psi for somewhere less agressive like bedford

Costco when you buy tyres there.
Just top up with air after I guess.
Someone mentioned helium.
Due to the fact it is a single inert molecule, I imagine it might diffuse through the rubber - anyone know if that would be so?
