Why is nitrogen gas is filled in tyres?
By KUMARASWAMY 03 March 2009

I think the main advantage is that nitrogen does not expand as air does when you drive the car (over a long distance for eg). In other words, the pressure remains constant. This also implies that you need not check and refill they tyres as frequently as in the case of air.

Answer by Anil 03 March 2009

People say Nitrogen gas is very light in weight, hence u can expect better mileage in highways...

Answer by Vijay Bhaskar 03 March 2009

hi , the reason you use nitrogen in tires is because
1) the Tyre does not heat up to dangerous levels over long distances at high speeds.
2) the volume of nitrogen is almost twice that of atm.air ,so you get the cushion effect.

now there is more to this ,the ride in the city conditions will be a little bumpy ,(till the tyre heats you to operative temp.)

Answer by Munaf Patel 03 March 2009

Air consists of 79% nitrogen and 20% oxygen balance being other gases.
Difficult to believe that 20%of the volume being filled could produce such negative effects as overheating etc. Nitrogen is an inert gas agreed......

Expert`s comment:

The advantge of using pure nitrogen is that it reduces the development of temperature of the air in tyres and hence life of tyre is increased .Hence its is mostly used in racing cars and aeroplanes.The fact that production of pure nitrogen is quite costly compared to the utility of the same in cars, it is not widely used in cars.

Answer by Shiva Shankar 03 March 2009

Air consists of 79% nitrogen and 20% oxygen balance being other gases. then why do you wanna fill nitrogen gas for 20 rs per tyre
total waste of money

Answer by Sadashivam 03 March 2009

car is car not aeroplane or jet so do not think to fill nitrogen gas in tyres of cars spl. maruti 800. on the other hand it is expensive too.

Nitrogen Inflated Tyres for CarsTowing a car to the petrol pump station after every few days to check air pressure is a tedious job. This can be avoided by inflating the tyres with Nitrogen as pure Nitrogen once pumped into the tyres retains the pressure for about six months. Besides this, it has many other advantages.

Compressed air which is normally used to inflate car tyres is a mixture of 78% Nitrogen, 21% Oxygen, 1% water vapour and other gases. Oxygen reacts very easily and when introduced into the tyres through compressed air penetrates the tyre walls and causes under inflation. This also causes the decaying of the rubber particles. Additionally, in an air inflated tyre, as oxygen enters through rubber there are possibilities of steel belts and the steel bead rusting.

Oxidation further lead to overheating reducing the life of the tyre and may also results in blow outs. An under-inflated tyre is very much prone to friction resulting in steering problem.

Whereas Nitrogen is a inert gas. Nitrogen is cooler, lighter, and does not cause any kind of rust on the steel or aluminium rims. As Nitrogen inflated tyre does not heat up, the life of the tyre is longer, braking is efficient, and also gives good fuel economy.

Answer by Kamal Maruti 800 Owner 03 March 2009

nitrigen is heavier than air as such it will not leak out moreover it will keep the tyre cool

Answer by S M Mittal 03 March 2009

nitrogen is a colourless, odourless, tasteless, and non-toxic gas that forms about 78 per cent of the Earth's atmosphere. this gas helps to reduce the tyre's running temperature as it acts as a coolant while the tyre are spinning.

Nitrogen gas would improve the ride's quality especially during a long distant journey.the gas helps to give more stability and handling control as it is lighter to normal air pressure.

Answer by Rraj 03 March 2009

nitrogen are basically used in air planes tyres so that they dont burst due to rapid increase in tempreture due to friction during landing as they keep tyres cool the only car that provides tyres filled with nitrogen gas in rolls royce and of that one tyre costs abt an average small car
