Thanks, R2D2 but I wish you'd inserted a 't' in my quote (bold)! Silly typo! By the time I realized the window period had expired!

my feedback regarding nitrogen
2 months after filling nitrogen -pressure still same
with air pressure usually drops in 2 weeks
after long drives at high speed-pressure difference is only 1 psi with nitrogen
with air pressure goes up by 4 to 5 psi

OK, a simple question.
Assume you start your long highway journey with under-inflated tyres, through some oversight. What happens then?
And if you do the same with 'normal' compressed air which has moisture?
Which of the above two scenarios sounds safer?

Think about this, though: if you fill your tires with air, the oxygen is more likely to permeate out of the tires before the nitrogen and over time you end up with a higher concentration of nitrogen. I have not checked this but it seems possible.

Are you sure the ambient temprature was exactly the same when you measured the pressures?

Actually its good that the pressure goes up on long drives!!

As for air retention, my new Yokos (on steel rims) seem to hold up damn well!! Even after a month I didn't notice any air loss!

Sir Einstein what an hypothesis. I fell off my chair after reading that.

PS: I know you are joking and the logic is irrefutable.

So to all nitrogen filling guys here's a tip - fill normal air, throw in some silica gel and let the oxygen molecules pass out of the rubber and you have the noble gas (literally) with its bigger molecules trapped behind. Oh my sides hurt

After reading the entire thread & getting the flash back of schooling with Physics & chemistry, I took my own decision to try Nitrogen for a fact that it would improve handling, road safety & smoother ride control.
I left my vehicle for service in Pratham Motors, the service engineer informed me that they wud charge Rs.100/= to fill Nitrogen in all the 5 tyres. Hope i feels good after the try.

I found the below information in one of the site : Just an FYI..

Nitrogen Information and Advantages

That was on my previous OEM S322 Bridgestone tubed tyres and got them checked for valve leakage but there was none. Also, a small puncture cannot be in same state for so long ( used those tyres for 36K kms) and situation was same from beginning.

I checked tyre pressure yesterday on my new michelin tubeless and guess what, its the same psi since the exact date 2 months ago when i filled Nitrogen when i got these new tyres.

Since the first fill was free of cost i had gone this route. Keeping all tech stuff aside, i can't complain now since i am seeing the benefit from it apart from the convenience of NOT going to a bunk for check every week

I like the nice, bright green valve caps!

You do realise that the above findings are listed by a company selling Nitrogen filling systems.

If Ingersoll-Rand makes nitrogen filling systems, there must be some value and market for it. It would not just be thin air!

Anyways - just my experience with N2 in tires - I've had N2 on mine since the last 10 months now. Have checked pressure around 6 times ever since the first fill. Just needed a top up once (2 psi diff.). Not comparing the ride quality and other stuff, but just the fact that my tires do not lose pressure is good enough for me!

In the interest of Science, requesting someone who really cares about this to fill N2 in the left tires and ordinary air in the rhs.

Run for a couple of days and check.

Just use the N2 pressure reader on all tires.

Yes, I saw that, even before posting my message !

Still searching for an independent assessment.

Wow, who would be that brave and totally experimental ( considering the the effort and time required) to do such a thing? I am sure there won't be any
