Its a precaution for users posted in interest of safety. "its rapid release in enclosed area", i said that. If anyone of us is sitting near the tyre and there is a sudden leak or if you are sitting next to a deflating tyre(like while doing puncture repair) you will not realize loss of oxygen partial pressure around particularly if the stream of air is directed at you. you dont have pure oxygen around you its air, which is already 78% nitrogen.
I hope its logical enough. i come from a industry which has to use nitrogen by rule in tyres.

I think what you meant was not that the direct stream of Nitrogen will displace the oxygen (selectively) but rather that you will be in a direct stream of Nitrogen! All the air will have been replaced by this direct blast of Nitrogen!

I'm afraid your wording made it seem like Nitrogen can displace Oxygen in some situations!

Friends,
Yesterday I have got Nitrogen filled up in my Scorp's tyres. This is done at one of my friends place which deals with Alloys & tyres. I went and inspected the equipment, really good and assures you the 95% Nitrogen for tyres. Fully automated and no loading from local cylinders etc.
So took the decision and got the tyres filled with Nitrogen.
The differences I noticed are
1. The ride quality is smoother
2. The car just glides now on bad roads with lesser bumps. Infact the shop owner pal forced me to take a ride post filling and we were taking the car over the manhole covers(above the road level) and bad patches.
3. The car also feels lighter
4. When on some open stretches, the car is put in neutral the distance covered in the 'glide' has increased than earlier!!!

This as per my friend will last for 3 months before a refill for any loss of air pressure!!

@getsurya - I would like you to do the same reviews after one week. And after one month fill in air and then do the same review. I would love to see the differences.

Vikram, I shall do the same. Are your questions out of earlier experience or just plain seeking review!

Ride smoother noticeably? It can be due to different air pressure. Nitrogen machines usually have very accurate air pressure guages. I think if you get same pressure air filled your ride will be similar.
Nitrogen makes a difference at race track demanding conditions, but its nowhere noticeable

Dude i have been riding on these tires for the last 6 months in my swift vxi but never came to feel a significant difference in the ride quality, thats what i got those filled for..the ride quality.

D1, TSK, Good points!! Let me keep a critics view on how this runs!!
As I have got this done free and was trying it out! But, I do feel a difference in the ride quality-thats a Fact!
Air pressure:32psi!!same as normal air!

Both. Out of experience and review also. Also invest some money in a good quality tyre pressure gauge and use it for checking pressures in your car tyres. Use this gauge for all experiments.

so it is still 50-50 i guess. I too filled up nitrogen for all 4 tyres. But sadly the tyres didn't last for a month. After that changed the tyres and filled normal air. For the few days i drove with Nitrogen filled tyres, the placebo was mind boggling.. Now i don't think there is any difference. REad somewhere that GTR comes nitrogen filled from the factory. May be the conditions are too demanding.
Vikram - i think you hate nitrogens don't you? :-)
anyway can you point me to good tyre pressure gauges? i would love to have one.

Well, here is one who LOVES Nitrogen!
But only as part of the air I breathe!

Let's be fair. There is no law of Physics or Chemistry that justifies claims of Nitrogen being superior in car tyres!
On the other hand, there might be a strong case for more research to be undertaken on this topic, to bring out hitherto hidden aspects or an entirely new theory to justify the claims regarding the superiority of Nitrogen over dry compressed air in tyres!
So perhaps it is best left to each user to decide for himself, for the time being!

I don't hate it. I have done enough experiments on the two vehicles that I have owned and used extensively to realize that it does not help in anyway except maybe in the placebo department.

Also a lot people fall for the misconception that the tyre runs cooler. I have enough data to prove that it is not true. People say that the pressure does not go down easily with nitrogen. My last pressure check up 4 months ago, except for a puncture that I suffered on my way back from Hyderabad. The remaining three tyres still have the same pressure as the day I got them checked. This is with normal petrol bunk compressed air.

Another interesting thing is that people say that air will cause oxidation and rusting of the wheel. Where as for rusting to take place there has to be moisture present. Without moisture there is no rust. Even the nitrogen cylinders that are available here have 90 - 95% pure nitrogen and the remaining is oxygen and moisture. So will this prevent oxidation?

For a good quality gauge you should contact any good tyre shops that you have there. They should be able to help you out.

Good quality tyre gauges are made by different companies for sale and for other tyre companies. Very rarely are they available in India.

I have one from Michelin. I have been bugging all the tyre companies to give me a bunch of tyre pressure gauges so I can sell it to people who actually care about their tyres. As usual, they havent bothered.

They dont understand that there are some people who actually know their tyres and want to keep a good quality pressure gauge.

Bridgestone recently gave about 5 pressure gauges to us to give it to free to certain customers. Beyond that, there is no help from the companies.

The gauges on air filling stations used to be notorious. However, the digital gauges now in vogue should be a lot better. I have both imported and Yenkay gauges and fid them quite Ok. However, I do change them every four years or so.

Correct me if I am wrong, but I thought one is not supposed to coast around in neutral like that, with both the engine's life and one's safety in question?
