Is it possible to use nitrogen to inflate tyres?
Is it possible to buy a small pressurised container of Nitrogen to top-up Nitrogen inflated tyres? I can get this done at my local ATS depot, but would consider buying a Nitrogen supply for emergency use.

It would be possible to buy a cylinder of nitrogen so you can fill your tyres at home, although it would not be cheap - expect to pay around £40 for 10 litres. It is also arguable whether there would be any significant benefits in doing so - the air in the atmosphere is 78% nitrogen in any case, and while nitrogen reduces the chances of corrosion due to a lack of moisture and reduces the rate of any potential pressure losses, it offers little or no dynamic benefits in how the vehicle drives in normal conditions.
From choosing the right tyre to what to do when it goes wrong - we have the answers.
