Last time I took thermodynamics, at low pressures PV=nRT. Since I work with compressed gasses for a living, I can tell you it's true!
The advantage of nitrogen? No oxygen, no moisture, and no compressor oil carryover. Oxygen permeates a little more quickly, but it also reacts with rubber. We have to perform oxygen aging and ozone resistance tests (as well as many other tests) to validate rubber for high pressure gas usage.
I agree with cold beers on using compressed nitrogen from a cylinder. Unless you use it by the thousands of cubic feet, it's much more cost effective to give a six pack to the local HVAC guy to fill your tires than lease cylinders or use this guy's service at $5 a pop! HVAC guys use nitrogen to leak test systems all the time, as it doesn't contaminate the systems with trace moisture!
Would I fill my tires with nitrogen? Not unless I was trailering at Z rated speeds (140 mph)!
Now you are talking my language. I just so happen to do HVAC work and have plenty of nitrogen on hand, bring that six pack on by and we will fill them up.
which one of you poor bastards wants to volunteer to pump up the tires on my tractor with that bicycle pump. I believe I could finish a case of beer before you get done.
I'll take ya up on that offer!
I hear you're kind of a lightweight so my plan is as follows.
I fugure by the time you get started on your third beer, you ought to be buzzing pretty good. I'll stop for a break and have a 5 or 6 beers with ya. You ought to be half bombed by then which is when I will execute my trojan horse!
I'll bet you another case of beer that you can't finish filling up the tire (remember you will be 10 feet tall and bulletproof about then). You will obviously attempt a victory and eventually give up since the tire is going nowhere. I figure you will either pass out or faint from exhaustion, which is when I will replace the valve stem I removed before I challenged you (probably when you went to "break the seal") and then, while you're passed out, I'll hook up a compressor...

Hey folks. Dont forget to change the air in your tires now that the seasons have changed.
That summer air is going to contract and your tires will be soft, resulting in excess side-wall wear and lower gas mileage during the cold months.
Leave the dense winter air in during the summer, and the heat might cause it to expand resulting in excessive tread wear and reduced traction.
(Written with tongue firmly in cheek. Just remember to check and adjust your pressure on a regular basis.)
in college we actually convinced a dumb@ss blond that was dating one of my buddies to get her air changed............the guys at the shop laughed so hard that she ended up crying.........they broke up and we got our drinking buddy back.
poppycock!
"fools and their money soon part" a wise man once said. for me, i'll continue to use "free" air in my trailer tires and simply check them at regular intervals.
Where you be gettin free air, there poppycock? It's .50 cent around my house. my air compressor cost me 475.00!
again, my original statement stands
but i can see that perhaps in the Palmetto state nobody has access to free air and the only compressor you can buy there costs 475.00.
the "free" air in S,Fla. is $0.50...but the pump never runs long enough to chk 4 tires so it costs a $1.00 to chk/fill 4 tires with "free" air...
Some of you guys are dumber than Dog $hit. All this talk about no moisture, no O2; well that may be true for inside of your tire if you use N2. The outside gets UV from the sun, lots of moisture and oh the dreaded O2. I have never had a tire of any type decay from the inside. If you think it makes a bit of difference to fill your tire with 95% N2 instead of 79% N2 go right ahead. We live in a free country and fools should be taken advantage of. Unless of course you live in NJ that the state takes care of you.

There is no FAA ruling to use nitrogen in aircraft tires. The only time it is called out is by the aircraft manufacturer, and this is only spelled out for high speed aircraft, alot faster then anyone drive or trailers!
O2 having an effect on rubber, doubt any of us have ever seen O2 rotting tire from the inside out. We wear tires out before any internal O2 rot takes effect. In fact everytime my tires get changed the inside usually looks pretty good!
I think we are on the next fad just like the old PTFE engine additive!

Lookey here fellas CB just called us dumber than dog $hit......We forgive you CB....We understand that technology may have passed you by lately but we want to help you make a name for yourself.....Go fill YOUR tires with hydrogen (all of em' including vehicle) , rename your rig "The Hindenburg" then let us know what happens
CB we get your drift. This was an information only thread....Never thought it would make three pages! You dont have to put N2 in your tires if you dont want to. You just keep using that old fashioned air stuff thats out of style.

I dont' really see the advantage of all the moisture reduction and all of that, but I can easily see where consistancy of air pressure could be an advantage. Have you ever started out on a trip, and checked your tire pressure at the start, and then again a few hours down the road? sometimes you will see a significant rise in pressure due to the heat buildup, just like a hot air balloon. If I can keep the air pressure basically constant by switching to nitrogen, I would consider that an advantage. If trailering for you only involves going a half mile and back to the ramp, I don't see what it would help, but for extended trips where heat buildup does happen, I can see where it could have an effect on tire life.
The lifting power of Helium would be reduced, since it would be compressed. And would escape VERY quickly. I hope we are getting some humor here, not meant to be serious.
Nitrogen, oxygen, helium.........
No one's said anything about methane. Always an ever-abundant gas at my house, especially after a meal at El Jalisco.......

Oh no. We're both from SC. I started this thread and it looks like you are ending it. Looks to have made it around the world though......

yeah..if I could figure out how to transfer MY methane to the car...I wouldn't have had to wait in line for 2 hrs for gas after wilma
