Have to agree with all the comments posted - absolute waste of time and money unless you own a F1 car.

The marketing bullsh!t will ramble on about the nitrogen keeping your tyre pressures constant and not expanding and shrinking unlike air! 

When has compressed air ever let anyone down?(excuse the pun) As long as you have good tyres and they are kept at the correct pressure, happy days  :smiley:

Gotta agree with DH on this one....


Having always had my tyres nitro inflated on my X-Type and BMW, I've always had the Gti inflated with Nitrogen too, I cannot sing its praises enough.

Not only do you not have to check your pressures for 120 days. But under hard cornering, there is noticeable increased stability in the tyres and braking distances are also reduced. Even if its marginal. I certainly notice the difference. Tyre life is 'supposedly' also increased by up to 25%, although my best guess through testing, is somewhere between 10-15%.....

I get mine inflated at ATS Kingsbridge, Devon (link below). They do it for a £1 a corner. I've never paid, but I usually come armed with doughnuts and/or beer!  :grin: (Maybe the same will work at your garage)

Here's a couple of links to back up Nitrogen inflation.

http://www.theaa.com/motoring_advice/safety/filling-tyres-with-nitrogen.html  (Sceptics, but still in favour, when used with semi-performance cars)

http://www.vcars.co.uk/news/generic-trend-stories/drivers-urged-to-consider-nitrogen-for-tyres-407.html

And here's a link from the wan kers that are Kwik Fit, that seem to think a mixture of Nitrogen and Oxygen, is what's required to realise the same benefits.

http://www.kwik-fit.com/tyre-technology.asp

Here's a little exert from the AA to completely dismiss their retarded claims and mis-information

"The air we breath (and the normal compressed air used to inflate tyres) contains 78% Nitrogen, 21% Oxygen and 1% other gases but some tyre specialists are now offering - at a premium - to inflate tyres with pure nitrogen."


There are a lot of sceptics that believe that nitrogen is a waste of time. They're wrong!

The reason for their scepticism, is that the normal air we breathe (as quoted above), consists of 78% nitrogen and 21% oxygen and thus simply increasing the nitrogen level by a futher 21%, will make only a minimal difference, if anything atl at all.......This is bullsh!t!

When you have this procedure completed, your tyres will be purged to 0.5-1psi, thus completely deflated and extracted of oxygen, then re-inflated with 100% pure nitrogen (which is stored in a canister at 2000psi+ to retain it's longevity and effectiveness).

I'd be glad to hear from others that have or currently use nitrogen, to see if they have the same ethos as me.

Thanks for reading.

:laugh: :laugh: - On road cars.... little to no benefit except it lines pockets of garages, and means the forgetful motorist can not bother about their tyre pressures for that little bit longer.

Reduced braking distances? :grin: Righto. That's a function of friction, velocity and weight, not what you fill your tyres with. N2 in your tyres will not make the brakes work better.

The benefit of it is that it is relatively unaffected by temperature thus the nominal pressure in the tyre does not change quite as much as with "air", example: check the tyre profile in contact with the ground of your car in the morning, and then once you've driven it for 10+ miles it will have reduced due to tyre heating the air and pressure rising. Less noticable with N2.

Oh and also, it's stored in a pressurised canister as that's the most efficient way to transport it, not to increase the "longevity and effectiveness". High pressure = larger volume = smaller container required to store it.

HTH's.

It's just more stable.
I use low volume magnesium wheels so that there's less air to expand meaning my tyres stay at optimum tempiture for longer.
Alloy wheels will give me no grip until up to temp, then plenty of grip to set 2/3 fast laps then due to the extra air they get too hot and go off.
N2 just slows it down even more. So I can put 1/2 psi more than air to get tyres up to temp faster but it will stay on temp until the end of race.

I might only gain 0.5 in a race distance but that could be a win in my eyes

where do you by yours to take to the track? I'd like to try some, using a 12v car tyre inflater at the moment.

Christ what pressure you running? I use a bike pump. Lube them up when popping bead on and it should only take 20psi. It's a stand pump.
We fill ours up at a car garage before we go. Just put them to 20psi then set at track.

There's good kits in America for superbikes. Then just fill the tank up at your local gas place.

Well that suits me down to the ground. And at £1 a corner, I'd rather not have to check tyre pressures every month. Not that I'm lazy or anything  :whistle:

Good set of stainless valves would do that  :wink:

Got stainless valves, even got little stainless valve caps with Gti printed on them....sad or what  :smiley:
