You catch on quick ...

 

Not quick enough to keep up with this crowd.

 

Do air compressors in Thailand not have water separators? 

 

i have to say my region of the US is quite arid and I remove moisture from my compressed air to keep airtools in good order so I have not felt how a bit of added moisture hurts a ride. 

 

Point of fact, we get terrible checking (cracks) in our tires from a lack of moisture. I reckon we would welcome more moisture content. 

 

Until reading this thread I had not been aware how personal this topic is to the rest of the free world.

On the other hand, if you can understand a slightly technical explanation then you will be 'wised up'  about the mechanism of transfer of molecules through rubber ...it's not as you seem to think.

I took the time to watch the "Auto Export' film twice in fact and yes he makes a number of salient points. However he over simplified, actually completely mis-understands, how gasses permeate through, in the case he is talking about, rubber tyres.

 

The paper that I pointed you to, and from your comment above, you appear not to have read. Written by Dr Keith Murphy of Air Products  and reading his profile on Linkedin states among other credentials was a past President of The North American Membrane Society ... google that if you wish.  I would believe his explanation rather than the 'Auto Expert'.

 

Dr Murphy states, after explaining why and how .... states that ' O2 "permeates" approximately 3-4 times faster than does N2 through a typical rubber, as is used in tires, primarily because O2 has a slightly smaller effective molecular size than does N2'.

 

Please stop digging ................

"  I would believe his explanation rather than the 'Auto Expert'."  

Your choice, of course, but, rationally, why would you believe him more than another qualified person?

 

" O2 "permeates" approximately 3-4 times faster than does N2 through a typical rubber, as is used in tires, primarily because O2 has a slightly smaller effective molecular size than does N2'."     

Maybe oxygen does permeate faster but tyres aren't inflated with oxygen!

 

Please dig more efficiently.

Question about water vapor under pressure.

 

Doesn't water vapor in a compressed air tank (under pressure) condense?

 

I drain my tanks of water each night.

I'll agree with what that link says, no discernible or practical advantage for road use at all.

 

unless 

Certainly, if you fall into one or more of the categories below, using nitrogen could be beneficial:

• If you have one or more cars that are primarily used at the racetrack
• If you drive very sparingly and your car sits unused for an extended time
• If you own collectible cars that are seldom driven any great distances
• If you have to put your car in storage for a significant period of time

Where do you get nitrogen for free in Thailand?

 

Cockpit outlet if you buy tyres,  don't know about other places l'm not on road much these days to notice.

Don't tell anyone l don't use nitrogen in my blade scoot tyres.

Water condenses from air if the pressure or temperature changes.  Typically when air is compressed, it is also heated by the compressor and then cools / looses pressure in the receiver creating condensate that is drained off.

Yes ...and if you are keen to have a really good explanation of how and why this article is for you ...  about-air-compressors.com/water-heres-why.html

So the OP was right, no benefits unless you're a racer (this was never about racers so it doesn't count) or you don't use the car ( in which case it hardly matters).

So tell us, is retaining correct tyre pressures for a waaaaay longer period using nitrogen over air that costs me nothing NOT a benefit..?

So nitrogen is not "free", it can't be if you think about it.  Nitrogen is commercially produced, it doesn't present itself ready for use or ready to be put in tanks, that costs money. 

 

Anyone who is getting "free" nitrogen when tyres are bought has the cost of it built into the tyres, very obviously, but some may myopically consider that to be free.

It would be a benefit if it was measurably a benefit but we're going over old ground now.  If you're happy thinking that you can overcome scientifically proven fact that trumps unproveable personal claims, then I'm happy that you're happy.

 

You haven't explained how you manage to get nitrogen for no charge, do you mean that the tyre supplier from whom you bought the tyres provides it?  If so, will they provide nitrogen that they have to pay for (it doesn't magically appear in tanks for use from nowhere) to non-customers who haven't bought tyres from them and where, specifically, is this generous place?

 

Let's assume that all the benefits that the nitrogen proponents put forward are measurable and practical facts for a moment.   If that is the really the case and nitrogen can be obtained free, literally free, without the charge being built into the tyre (and the same nitrogen supplier's) prices, then why is nitrogen not available free of charge everywhere, for everyone, in place of compressed air which, according to some,  allegedly costs the same (i.e. nothing) and has major disadvantages?
