The use of Nitrogen to fill tubeless car tyres is becoming increasingly popular in the country today. Thanks to its advantages over regular compressed air, an estimated 30 per cent of Indian car owners in urban areas perfect to use it today. In its purest form, nitrogen is a naturally-occurring, non-flammable, dry and inert gas that can safely be used for tyre inflation. In fact, military vehicles, aeroplanes as well as Formula 1 cars have been using it for years.
The main advantage is that nitrogen is much better at retaining tyre pressure over long periods of time, preventing the hassles associated with under-inflation. While both nitrogen and oxygen (a constituent of regular air) permeate rubber, pure nitrogen does it slower, taking up to six months to lose 2psi, compared to just one month with normal compressed air. The reason is simple – a nitrogen molecule is larger and does not seep out as quickly as oxygen.
Nitrogen also disperses heat quicker than compressed air, rolling resistance, providing better fuel economy, extended tyre tread life and reducing the chances of tyre failure. Also, since nitrogen is dry, it eliminates wheel corrosion from the water vapour found in regular air. An increasing number of petrol pumps are now offering this service around the country, though data shows that nitrogen inflation has gained greater popularity in the west and the south of the country.
Earlier, tyre shops had discovered that nitrogen filling was a perfect way to increase their revenue and charged around Rs. 100 per tyre. Lately however, the cost has declined to around Rs. 20 per tyre, while some dealers even offer free for inflation for new tyres.

Gone are the days when tyres were filled only with the air. Now just like replacing or upgrading other car components we can also replace the air tyres with nitrogen filled tyres.
Nitrogen is was used in aircraft tyres, military vehicles, racing bikes and the also in the Formula one cars
. It is often said that Nitrogen inflated tyres are better performer than the air inflated tyres. In the air tyres, there oxygen leads rotting of the rubber particles. But in the case of nitrogen inflated tyres as there is lack of oxidation, the nitrogen does not escape and gives better life to the tyres.
I am not sure I fully concur with you on this post. Even so I am normally amenable to new ideas. May have to feel about it. Great blog anyway.
Of course, what a great site and informative posts, I will add backlink – bookmark this site? Regards,Reader.
