Guys, these are the basic facts.

the difference in ride quality or performance is so small, none of us will notice it.

If you want to know the REAL advanatages of inflating your tyres with Nitrogen, it's this.

1). Lesser trips to the petrol bunk to top up your tyres.
2). Since Nitrogen's pressure varies less with temperature, the pressure remains constant which in turn helps tyre life.
3). When you have alloys, oxidation is reduced on the inside of the rims because there is no Oxygen to oxidise and corrode the alloy wheels.

Basically this is it.

It's upto you whether you think the extra money you pay for Nitrogen is worth it or not.

Quite some time back I posted my opinion on nitorgen filling in this thread itlself.

I went for Nitrogen simply because in Delhi it is free(Opposite Bhikaji Kama Place), and I was passing by that way.
Before trying out nitrogen, I had ordinary air(32PSI) in all 4 wheels.
Then I parked the car for more than 2 months, and when I came back the pressure reading was around 28-29PSI.
So all in all I lost 3 PSI in 2 month 10 days.
Now also I get air checked every 3 weeks or so at the petrol pump where I fill and the pressure drop is 1 PSI, and in some cases none.
All my checks and filling is done when its night and the tires are cold.

The only benefit I can think of is that the Nitrogen will have zilch moisture content so your heat/cold air pressure diffrential will be low. this will reduce the chance of blowouts if you are driving very near to the speed rating of your tire.

For example if your tire is rated for 160kmph, at 170kmph the risk of blowout with ordinary air will be much more than risk of blowout with Nitrogen.

So all those guys who have 160kmph rated tires and drive at 170kmph please use N.
As for me, I have 210kmph rated tires and the top speed of my car is 130kmph, and I do sustained high speeds at 110 atmost, so ordinary air is great.

Of course whenever I pass by BKP, I go for N, because its free, and the IOC pump has good fuel.
But paying 30rs/tire... Well I suggest you try the Almond fudge cornetto, its very tasty.,
Don't eat 4 together, else you will get tummy ache.

BTW, you do know that you cant check the tyre pressure at one petrol bunk and then compare with a reading from another place.

Unless you have your own tyre pressure guage, you cant get an accurate reading. The best you can do is to measure it at the same place everytime.

I have my own tire pressure guage.
I try to keep the reading at 215Kpa approx.
This corresponds to 32PSI at the pump where I fill air(I mostly use that pump).

Infact whenever the pressure drops to around 205Kpa, I go for air filling.

i filled up Nitrogen for my Swift Vxi tires at Coimbatore, as it is free of cost at an IOC pump. But when filling up, they pasted a sticker in the windshield saying that "Tires are inflated with Nitrogen".

I was also told that if I fill up Nitrogen once, I should avoid filling normal air in that tire. Is it true ?

Chemically speaking there could be a case for this but there are many more factors at work and unless your tire are leaking (in which case nitrogen will not be of much help either) there is hardly any practical advantage in normal course except you wallet shedding some weight and consequent FE improvement ;-)

Ohohohoh also Nitrogen is lighter than Oxygen (look up periodic table) so replacing 22% of balance air with Nitrogen will also shed some milligrams of weight even if you biggest rims.

Gents,

I think NO2 & air requires different gauges as My observation while checking Nitrogen & air with the same gauge giving different readings. The NO2 was showing 32psi when NO2 gauge was showing 28 psi. so to crosscheck we tried my gauge on air, it was showing actual reading. I realize by this practical experience that we need different type of guages for different gases.

Very Funny! Yeah, me too thinks that will give you more bang for your buck. Or if nuts are not your thing, you could try the fruit overload. Sorry, could not control myself!

Travel-X, I really hope you mean N2 and not NO2. NO2 is poisonous and deadly.

Today i have filled all my 5 wheel with nitrogen at MSM chennai. They charged Rs50/- per wheel and advised me to check the tyre pressure every two months. The top up will cost Rs10/- per wheel.
I was given a flyer and the following is mention as the benefits claimed for using nitrogen over compressed air for inflating tyres:
1) Reduce the tyre's running temperature.
2) Nitrogen improves ride quality.
3) Nitrogen increases tyre life.
4) Reduced pressure build up.
5) Pressure loss is slower with Nitrogen than with air.
6) Nitrogen doesn't react with metal wheel rim or the tyre materials.

Note:- I don't understand the 4th point.
Maintenance:
Once your tyre are filled with Nitrogen it's important that only Nitrogen is used for top up purpose adding normal compressed air will negate any benefits of the Nitrogen.

50 bucks a wheel. wow. You got conned. Sad to say. It costs 50 bucks for all 5 tyres or at max 75 bucks. top ups should be free.

What happens is in many places (read as tyre showrooms or service stations), they have limited space and there is generally a huge rush to fill Nitrogen in the tyres and the other customers who come for something like tyre changing or wheel balancing have to wait or there is a mini traffic jam in the shop.

So, some places purposely charge a lot for Nitrogen inflation to manage the crowd. Something like how Mainland China doubled the rates for it's weekend buffet and now find it so easy to manage their crowd.

May be not in chennai i guess, well i am not sure. But i do agree that Rs50/- per wheel is expensive. Cost will come down once many people start filling Nitrogen instead of compressed air.
