The second side of the coin is that the compressed air available in our petrol bunks is always loaded with moisture as they do not see it fit to use an air dryer along with the compressor. They just use a small air filter and think that it is enough for drying the air.

Nitrogen that is available over here is relatively dry when compared to the above mentioned compressed air. Hence it make a very small amount of difference.

I use dry air and find it much better than nitrogen. But not everybody has access to dry air.

I told my petrol bunk guy to invest in an air drier for his compressor which costs about 50k. He said saaar too expensive saaar. When 50k is expensive then do you think they will spend 2 - 3 lakhs on a good quality N2 generator. Dont think so. Also if petrol bunks started using air driers then nitrogen would become obsolete.

And oxygen and nitrogen dont expand too much by themselves because of heat. The water vapour or moisture is what causes the pressure to change due to heat. I have access is 99% dry compressed air and I have found that this air behaves much better than nitrogen that we use. But one thing I have noticed from my experience is that the ride quality is better with nitrogen than with dried compressed air.

And what you have said about 90% purity of nitrogen is not true as even the most commercial nitogen available is 95% pure.

Vikram i see that you were a fan of nitrogen filling back in the days. and i also came to know from where one can source "dry" compressed air in bangalore. Totally agree with you "dry" compressed air and nitrogen filling will give similar results, the key word here being "dry".

No compressor will produce dry compressed air or dry nitrogen. 'Dryness' has to be achieved by deploying dryers, silica-gel based or refrigeration type.

True, getting 100% dry compressed air is a costly affair. however, nitrogen pumped out by the N2 generator installed at the fuel pump will be many times drier than the normal compressed air

Most nitrogen filling machines give "dry" nitrogen, as they are designed to take in air, and remove all other gases except nitrogen. So you have 99% humidity.
But even so I don't think if you are filling your tires properly with ordinary air you have to worry about pressure variations unless you are running on a racetrack

Is that a typo?

It seems it is now fashionable to fill tyres with nitrogen, never mind the actual advantages. Next step: Beer shampoo for the paintwork.

Oh yea typo. I meant 99% pure N2

You can fill Nitrogen at the Jubillee Hills Check Post Petrol bunk.

Price: 40 Rs per tire. 10 Rs per tire for topups.

PS: I don't use Nitrogen in my tires.

Oh I had completely forgotten about this thread. Yes I used to be a fan once upon a time but soon came to realize that N2 was overrated in all aspects. I have a refrigeration type air dryer and am very happy with compressed 'dry' air.

Now that is a luxury most of us cannot afford at home! And even if I did invest in one, how would it help me if I do not also have a compressor/reservoir system at home!??
Now, let's suppose I am rich and go in for one of these thingys too.
What happens when I go on longish holidays?

I don't have it at home. I have it in my factory for feeding my CNC machines with dry air. I have just tapped one of the lines for use with my car.

When on a longish holiday rely on petrol pumps or carry a small 12V compressor like I do.

I do! I have the SLIME smart sport duo!
But with Slime in my car tyres I have never had ANY problem so far! Ladakh, Jalori etc. notwithstanding! Nearly 15 months now!

alright one more new place with special price in the city nice find mate, now i am off to that place.

[speed0mania]

i dont know whether it was the well calibrated pressure guage or actually N2 but my car felt smoother after it! sadly you don't get it anywhere in Delhi anymore! not that i know of. i was thinking, i have a compressor at home, if i fill the reservoir tank with lotsa silica gel packets, would it actually give me dryer compressed air? i know it cant be completely dry but what do you think would be the difference, i'm talkin fillin it up something like 10% its volume at least!?

With Nitrogen, the omni also feels a lot more faster, especially around corners. I filled Nitrogen in the tyres of our 2 decade old Omni and now i can take that roundabout at speeds of 40kmph instead of 38 kmph. Even the ride has got better the leaf springs on the rear suddenly feel like gas filled shock absorbers.

The Nitrogen has also reduced the tyre noise and makes turning the steering easier, it's now as if i have Power Steering.

Even though i stay barely 400 meters away from the sea front with 90% humidity all through out the year, after i filled nitrogen and due to the awesome characteristics there is no rust at all. Only the rims are getting saved though the rest of the body is still catching rust. Maybe I should make the whole van airtight and fill it with Nitrogen inside the cabin that would stop the rusting. But then how do i drive?

Even the local air filling fellow who got a new Nitrogen pump, owns a Audi R8. Nitrogen is helping everyone.

[motionfreak]

i don't know about the better road holding or tyre temp, but with Nitrogen my car's tyre noise has reduced considerably.
It matters to me considering that I use 195 section tyres
