Are you implying that "on the rocks" is an incorrect way to enjoy Bourbon!

Them's fighting words. I challenge you to a tasting competition. I already got the campfire going. Now, I do try not to allow my libation to get too watered down but I do like it chilled. Excuse me the cooler by my chair just knocked.

Oh yeah, check your tire pressure regularly, see owners manual etc.

Ok - I can see it now. A "hitch equivalent" thread on bourbon, whiskey and scotch - how to drink them, how not to drink them, what's the "best brand" (mine projects the "pivot point" toward my rear axle, yours doesn't carry enough weight), rocks, no rocks, metal cubes, granite cubes, distilled water splash, chilled, warmed, crystal rocks glass, red solo cup, Glenlivet 18, Pappy van Winkle 21, Woodford Reserve, Sazerac 18 Rye, Johnny (red, black, blue)...

On second thought - let's just toast each other and get on with it :-)

How about adding 1792, Bulleit or my campfire special, Rebel Yell. Any in a Mason jar on the rocks thank you.

Check your tires every time you stop, give em a glance.

PV = nRT This thread is subject to massive thread wander. Amusing, but not scientific. Race car logic is the same. Lots of unproven theories and urban legends. Since tires are usually just filled with nitrogen, rather that 100% purged of all oxygen (a physical impossibility), the possibility of having a tire filled with only nitrogen is extremely remote. The potential benefit is also infinitesimally small. Interesting waste of time and money.

Me , who call myself tire-pressure-specialist now, also now concentrating on Nitrogen filling.
Planning to make an article in wich I first sum up all the comercial arguments, then de-mith them or relativate them .

One thing i can already de-mith and that is Nitrogen ( further N2 ) absorbing more heat then Oxigen( O2) , so your temperature and by that pressure stays more constant, for instance when braking .
It is true if you use per mass so per lbs , but as is used in tires in volume , even O2 absorbes ( 1% ) more energy . So this mith can even be deforced because its simply not true.

Busy now on the argument of rubber having little holes in it troug wich the smaller O2 molecule disapears quicker then larger N2 molecule.
But what then at higher pressure ,do the holes get larger so N2 goes yust as fast trough them ?
To my conclusion difusion trough the rubber is a much more complicated matter , somewhere between Phisical and Chemical, so the more reactive the molecule the quicker diffusion.
Then it could be that Helium ( He) althoug its a smaller molecule but totaly inert gas , could even diffuse slower then N2 troug the rubber.
Also Argon is an Inert gas and saw someone mention it here already.
Could be that Argon even dont diffuse at all , and its a side-product of Amonia production , wich is used for artificial vertiliser production, so probably in the same price as Nitrogen.

The rate of diffusion is sayd to 2 or 3 times more for O2 then N2. Even 5 times is mentioned, and I use that in spreadsheet I made. Then this results in less then 2 times more pressure loss for a 80/20 filled tire then a 100/0 N2/O2 division. Then in about a year I think the 80/20 tire looses 10% of its pressure and the 100/0 filled tire "only" 5,8%. Before that you have already checked it tree times if you are wise and filled that small difference of 1/3 th of 6,5 psi on a 65 psi filled tire . The N2 then only looses 3,5 psi in that year .

Filled in my spreadsheet with Argon 98% rest O2 and N2 and asuming argon diffuses 0.1 times as fast as N2 , and then even pressure rises about les then 1 psi , because O2 and N2 diffuse into the tire so more gas is coming into tire in time.

To determine the diffusion factor in compare to N2 ( =1, O2 = probably 5) I thougt out a test with 4 old the same tires with same rimms ( from old car or winter tires when summer) . give them a basic filling empty tire so Zero pressure = 1013 milibar real pressure , with same gas compound as outside
Then fill up with 100% each tire , one N2 two O2 , 3 Helium, 4 ARgon,
then the pressure loss is totally because of the diffusion of that filled gas , because the ground filling is Partial pressure of N2, O2, AR the same as outside , so yust as much of those gasses diffuse in as out.
The diffusion factor then can be calculated yust by deviding the pressure losses.

This would make the diffusion factors for shure and no gambling about it.
My expectation is that it will prove Ar and He to have a diffusion factor of 0,1 or less.

Then last about Water in the tire, my idea is that a little liquid water can help cool down and transport the energy better then dry air.
This because of the energy that is needed to go from liquid to gas ,
The pressure in tire will rise a little wich then gives lesser deflection so lesser heat production by the bending of the rubber.
but first I have to know how to calculate with that, so placed a topic on Dutch science forum about it, but had also to do with partial pressure of water as gas for a sertain temperature before it condenses.

If air has a greater coefficient of expansion than N then from an economic aspect maybe air really would be better than N? Think hot air balloons. If air in tires gets hotter than N then it would try to rise and so take weight off the trailer which would equal less fuel consumption and less wear on the tires.

The possibilities are boundless. Instead of conventional insulation between the inner and outer skins, how about using balloons filled with helium? And all that wasted space in the chassis box girders. If one got too much lift could traction problems arise? Once when I was working a job I didn't like, the air and everything else seemed heavier on Mondays. So should Mondays be a stationary day?

There's a multimillion dollar government research grant somewhere in here guys.

This is really a chemistry question. The molecular size of nitrogen remains relatively the same under increased pressure and heat vs. Oxygen. Nitrogen is a smaller molecule. It can make a slight difference if you generally drive 200+ miles per hour. I have never seen a service station that has a system that effectively evacuates all water and oxygen prior to filling a tire with nitrogen. For regular everyday driving, it is a gimmick. Steve

Now look here Dwight. You should know that Airstream owners consider any discussion of Airstreams a serious matter and it could be that some may consider calling their discussion of N "amusing" somewhat of an affront.

Na Zdorovie is a Russian toast. We always say Sto Lat! It's a Polish toast / song for all happy occasions. May you live 100 years; bottoms up! . I'm half Polish, not sure which half, left / right / top / bottom. So far it hasn't mattered much

If she is a she would her nickname rather be "Ska"

But In my last ( and first) post in this topic, I mentioned that the difusion rate in my test, could simply be determined by deviding the pressure losses , but that is not true.
Have found a way to calculate it thoug, so my test can be done still.
Tried it out that calculation and if for instance 100% N2 filling to empty tire looses 10% and 100 O2 filling 50% in that same time, it calculates not 5 times, but 6 to 7 times that O2 diffuses quicker then N2.

If in a few years Nitrogen is replaced by Argon, then remember it was my idea.
Argon though is a "heavy gas", also used in Air-bags, light bulbs.
So it would make the vehicle a bit heavyer wich we cant use ( about max 1lbs) so this would give Helium an advantage wich makes the vehicle about 2 lbs lighter.

Argon is used in low-e window glass and if the windows are shipped over high mountain passes too fast, the seals don't have time to adjust to the lesser air pressure and weaken and eventually fail. Those of us who live in Colorado check to see where the product is shipped from so they don't come over high passes more than 8,000'. If they do, follow the truck and make him stop every once in a while to allow the seals to adjust—lots of luck with that.

With argon in the tires, you'll have to stop at 8,000', wait a while, go up another one or two thousand, stop again, and so on. Enjoy the beautiful sights, have lunch or take a nap.

Tires are not that rigid as window glass , so the tire yust has higher pressure then wich it can stand easyly.

Would the same problemm be if the low-E window was filled with any kind of gas?
