    Nitrogen in tyres

    I've just been browsing a tyre website for a quote, and it told me that for an extra Ł1 per tyre, I could choose to have them filled with nitrogen.

    Has anyone heard of this before? What are the benefits of it?

    Its supposed to be an inert gas wich does not expand too much from when the tyres get hot and they will also save mpg. Its also denser than air wich means it wont excape that easy ... I would say its just marketing rubbish...gasses will behave symilar in the same given condition.

    I suspect you're right, given that air is already 78% nitrogen anyway.

    True about the 78% of nitrogen, but you need to think that around 20% is oxygen and how much that expands.

    I know from a track day, my tyre pressure on about 8 laps were increasing from 34 to 46 on air.

    still gonna be higher percentage of nitrogen. but yeah its a valid point.

    Hi

    Filling Tyres with Nitrogen
    Beneficial in specialist applications

    The air we breath (and the normal compressed air used to inflate tyres) contains 78% Nitrogen, 21% Oxygen and 1% other gases.

    Purified nitrogen has been used to inflate tyres on aircraft and racing cars for many years, but now some tyre specialists are offering nitrogen inflation for ordinary car and van tyres.

    The advantages of using nitrogen in specialist applications are clear

    Planes fly at heights where temperatures may be as low as -40C. Any moisture in the tyres can freeze causing vibration and balance problems when landing. Pure nitrogen is dry so eliminates this problem (as would using dried compressed air)
    In motor sport the smallest fraction of a second can make the difference between winning and losing. Filling with nitrogen can reduce tyre pressure variation caused by changes in tyre temperature.
    For passenger car applications the main claims seem to be

    Reduced corrosion – because unlike air there's no moisture in pure nitrogen
    Slower rate of pressure loss – because nitrogen molecules are larger than oxygen molecules (which make up 21% of compressed air)
    Leakage can occur through the tyre's inner liner but can also occur through the valve, punctures, or failure of the seal between tyre and wheel rim. Pure nitrogen might leak more slowly through the liner, but regular checks of tyre condition and pressures will still be essential.

    Corrosion of the tyre through use of normal compressed air alone is most unlikely because only the outer tread band of a car tyre contains steel – the amount of moisture reaching it from the inside is minimal.

    Changing to nitrogen involves removing all the air which is already in the tyres and then re-inflating them with purified compressed nitrogen. There will be a one-off charge per tyre but once filled with nitrogen any future top-ups would also have to be with nitrogen if any advantages are to be maintained.

    Overall, while accepting the possibility of purified nitrogen being of benefit in certain applications, we don't think that the cost and possible inconvenience are justified for normal passenger car use.

    Less chance of leak though, so less reason for them to need pumping up.

    If you got a puncture wouldn't you suffocate?

    And what if they explode?

    No

    and they wont, less chance of these to explode as no moisture in the tyre = less chance of a blowout.

    If they did go pop, it'd just be the same as air.

    ok then, so what major national dealership will offer you such a service should you wish to have your tyres filled with Nitrogen?

    Technical, if you'd rather take it to German im fairly fluent

    All gases react different. The oxygen in air has a habit of forming water droplets under extreme preasure for one. Nitrogen is fairly non reactive hense why they use it in crisp packets. It is also why as above they use it to fill the tyres for race cars etc. Again for average joe public maybe not relavent. But if you like to take her on a track day every now and then i get my track wheels filled wth N2

    If you really want to get technical i can explain how the tripple bond make up of the nitrogen gas is incredibly strong, and causes said effects.

    Its ok James, I'm with you on this one, when I first saw this I thought 'what if a nail goes through and catches a radial cord?!? Ka-boooooooooom', but it appears the scientists among us have squashed all of our concerns!!

    I think I've decided to stick with normal air. It's served me well this past 47 years.

    Now I just can't tell if you're joking, nitrogen isn't flamable?

    Apparently its not combustible, which is a huge shame, I'd love to see some insurance claims using that as a reason!!!

    I'm glad its not! Most fire suppresion systems in the world are charged with nitrogen :| lol

    Nitrogen for car tyres = inert and dry, so less chance of pressure change as tyre temp changes.... and less chance of corrosion.... but tbh you're 80% of the way there with clean dry air, so get it done a the garage in the first place and then top up with a decent air compressor (i.e. avoid the footpump).

    I'm sure I've had the nitrogen option for free most of the time...
