    Air is approx three quarters nitrogen.

    I think that it is supposed to run cooler and also to less effect on the rubber compounds as oxygen may cause the rubber to eventually degrade!
    For this reason Citroen suspension spheres are filled with nitrogen.

    Redefining tubular ;∑)
    Only advantage of nitrogen-only: gets rid of the oxygen*.
    Oxygen oxidizes things. Like tire rims.
    Yeah right. That nitrogen cylinder is now a must-have in your luggage.

    * And of the carbon dioxide, which, although it's only .04% of air, is responsible for everything from acne to 9/11... not to mention catastrophic global warming

    The main benefit is that pure nitrogen expands much less as it heats up. The moisture content in normal compressed air leads to significant pressure increases when the tyre gets hot. Nitrogen fill is therefore useful in race cars where consistent tyre pressures are critical.

    Paying extra for a nitrogen fill on road car tyres is as sensible a use of money as using $10 notes as fire starters.

    Default Marketing opportunity !!

    Hi Kevie
    Similar to a lot of our obsessions, like V8 engines, very low profile tires, smart phones, fast food etc ect ect, nitrogen in tires is a marketing opportunity to the gullible public !! Come in sucker.

    Some 0.1% of truth against 99.9% of profit. Capitalism at it's best.

    Jaahn, that's just a little cynical.
    I'm a car enthusiast and I enjoy treating my cars well, making improvements and mostly that means taking the more expensive option like using PULP fuel, running on the best original tyres etc. when it comes to my cars Im not a penny pintcher. So for what is a relatively minute amount of money I'm running nitrogen in the TRXs on the CX. If it gives me more life on the TRXs then I'm the winner, if it gives me no real benefit at least I had some fun in the process.

    In fact the tyre centre topped then up yesterday to my requested presures for no charge.

    Jaahn, I rather enjoy the lazy powerful torque developed at only 1700RPM whilst cruising at 100 KPH in my 5 litre VT Calais. It is a great car and I still average around 11 litres per 100 k in a mixture of town and country driving.
    Please don't knock the V8. I probably like you never thought that I would buy an 8 but one day this car came along and it has changed my mind.
    Cheers Gerry

    I completely understand that, regarding the V8 Calais. I do agree with Jaahn on the low profile tyres and nitrogen argument though. Most people drive in the circumstances illustrated in the attached photo I suspect, with occasional bursts of speed.

    I suspect dry nitrogen inside the tyre/tube must be slightly better than moist 80% nitrogen, 20% oxygen (approximately) but then I think of what the OUTSIDE of the tyre puts up with, including UV radiation. I've found I can only get about 15-20 years reliably out of tubes using raw air.

    I'd put the nitrogen money into tyres that stop well on wet roads myself. It looks as if Adrian has done both good tyres and dry air.

    Cheers

    hey thats great information ;what about filling the tyres with hydrogen it may float like
    the first air ships.

    Make certain you also evacuate the air in the tyre before filling with Nitrogen as the F1 teams do

    Now.. significant is not really the adjective I'd use.

    From
    Nitrogen for Tires: Question #1

    "The first thing to notice is that throughout the entire operating range of the tire, cases #1, 2, and 3 are virtually identical, differing by no more than 0.04 psi at 110F. In other words, it doesnít matter whether youíre using desiccated-dry air, moist air from a 150-psi storage tank, or dry nitrogen: all three mixtures respond the same, with negligible difference, to temperature changes."

(2) Bragging rights. OK, you were behind the curve with cell phones, iPods, thong underwear, etc. Nitrogen in tires is relatively new to the mass market. Now's your chance. (3) Reduced fire danger next time you land your space shuttle or commercial aircraft, and tell me you won't sleep better knowing that."

    You called me cynical ??

    I used nitrogen exclusively in my tyres for much of the '80s. But that was because I worked for CIG/BOC, I had a company car, and our transport garage (where the fuel bowsers were) only had nitrogen connected to the 'air' hose for topping up your tyres. The reason for that was simply this - why run a garage compressor when there was a compressed nitrogen line available in the adjacent cylinder filling plant?

    We supplied nitrogen to the commercial airlines, RAAF, mining industry, and large transport companies. It was also used in racing tyres and we had a crew at the MotoGP at Philip Island for several years providing nitrogen for the bike tyres. All the benefits quoted are correct - but unless you're running a large long-distance heavy transport fleet where the benefits are cumulative, you won't even notice them. You won't notice anything with private car use, and I doubt you'd even notice it across a fleet of taxis.

    Like WLB says,not worth the money to bother in passenger cars,only race cars.
    did some work for road train operators and they used nitrogen due to the heat and the weight of the rigs,they said it was worth it.

    I think it all has to do with Boyles Law.
