Hello, Waste of Money.

http://www.jaffacake.net/dx/nitrogen-nonsense The effects of nitrogen Vs Air are similar, like if you sneeze whilst driving you will have less MPG and your 0-60 times will be affected.
It's on the Internet - so it must be true! [
] I've used N2 in my 911's for many years and, in my experience, it is worthwhile. My OPC has a kit and a fill costs between £10 and £20 - not a lot of money and I get consistent tyre pressures that don't fluctuate much - even after hard driving and I hardly ever top them up. The trick, of course is to purge as much air from the tyre as possible to eliminate moisture - the tyres usually need filling and purging several times. Also, pure N2 from a cylinder is much better than gas extracted from air. Ideally pressure readings need to be adjusted at 20 degrees C, which is the ambient temperature recommended by Porsche. Dried air can also be used if available and works in the same way. [] Regards, Clive.

Unless 100% air the air is sucked out then its not pure Nitrogen there's still moisture and pointless doing as the benefits are beyond minimal. I never have to check my tyre pressures because my rims have no leak and my schrader is done up. Most schrader valves leak from the factory and that's why most tyre's need air frequently. Get yourselves a Schrader tool.

thanks for the input guys, i did wonder if it was just another moneygrabbing spin by garages.

It costs enough to keep our cars on the roads without throwing away good money on gimmicks like Nitrogen fill in the tyres. Air does its job and unless you are racing and going for repeatable perfect lap times on lovely smooth surfaces then forget about nitrogen. How well do your tyres seal against the rims? How many pot-holes do you hit? How much sidewall flex do you get and how often do you need to keep topping up your tyre pressures? Waste of money on the roads, definitely.
Actually there is. Now retired, but I have a vehicle refinement background and we often used a nitrogen fill to change the tyre acoustic cavity mode to see what effect it was having on interior noise. Sometimes the cavity mode can couple strongly with the suspension components to generate structure-borne noise, or it may just find an airborne noise route into the cabin. So, Lancerlot, your car might actually be quieter than the those of the non-believers..! Jeff

Actually, "Not non believers" Just think its better suited to a Nascar sponsored team than going out to the supermarket.

Had mine done for free at Kwik-Fit but they only charge £1 per wheel. I read up on this and I thought the tyre wear was extended as Nitro prevents rubber corrosion, plus the pressures remained constant for longer period. John
Jeff, Neither have many of the posters here, I would suspect! [
] The OP asked for opinions on N2 fill and he's had them in spades. My offering, for what it's worth, is that it IS advantageous - but that's only based on 30 years of Porsche ownership and neither do I use my car just for transport or supermarket shopping expeditions. [] Also, it occurs to me the more power available, the greater is the benefit. If I waltzed into my OPC for N2, a Porsche trained technician would fill and purge each corner at least 3 times, using calibrated equipment and it would likely take ½ hour or so to complete. I do not therefore think a £10-£20 charge would be at all unreasonable. If I were buying tyres there, then I've no doubt nitrogen would be included at no extra cost. [] Nothing like a good, healthy debate. [&:] Regards, CliveSamanthaHewit

errr isn't normal air made up of 78% Nitrogen anyway? So why the hell would anyone want to pay money for 22% worth of 'non-air' ??? Am i being dumb here but british roads are not good enough to reach the full potential of our cars as they are? Let alone with 'Nitrogen enhanced' tyres. what is the point????[8|]
