Poll : PURE NITROGEN ( Z ) in tires - Page 2

Bruno:
Please do not take offence. I am sure Sander17 was making a little American humor. In the USA we often joke with each other in this manner. Same with my response to Sander, was an attempt to upstage his humor with a more ridiculous addition to his proposal.
If you make a trip to the Bordeaux region, I have a friend there with a vineyard who drives around France in a Cadillac STS (with Minnesota licence plates), and has a dog named Fluffy. I helped him pick his grapes a few years ago. He would love to see your Aristream.

Bruno,
Please do not take offense. I don't care what hat you wear.
The point I was trying to make was that just because two events happen simultaneously, it does not necessarily mean that one causes the other. In your previous post, it appeared that your filling of tires with nitrogen caused the uneventful trip. All I was implying was that you probably would have had the same result using plain old compressed air. Did you have a previous trip with lots of tire problems from using air? If so, we should investigate why such problems are not seen on this side of the Atlantic.

Once again, I am sorry if you took offense to my response. I guess humor is difficult to translate at times.

OK; Thank you for your courtesy So...
I let the nitrogen in my tires

Best regards from FRANCE;

Doesn't anyone want to discuss using Argon as a tire filling gas?

I'll Bite

Would enough static from the dry roads make your tires glow??? Too bad they would glow green? Blue would be the rage fer sure!

Think about the arguements of "Can I pull a 34' classic with helium filled tires with my '98 Kia?".

theNewkid:
Actually, I hadn't thot of the glow factor. I was thinking that argon has lower thermal conductivity and diffusivity than nitrogen.

Okay, after reading the posts, I have this to add (or detract):
Farm tractor tires are filled with salt water for increased tire weight and traction. If you don't put the salt in, the water will freeze in place in cold weather, making for a bizzare ride.
Europe has relatively high speed limits, compared with ours. If you travel on the Autobahn, for example, with no speed limits in most places, you will most likely be traveling at speeds that would benefit from the Nitrogen. Most freeways here have a limit of 70 or so, not really high enough to warrant the straight gas.
As far as I know, Nitrogen will not cause any problems with your tires, if you want to use it, other than the obvious issue of transporting a full cylinder of the stuff on the highway .

Nitrogen's main advantage is that it does not expand at the temperature normally encountered in automotive and trailer tires. Airline jet tires are filled with nitrogen for this very reason, they run about 200lbs of pressure, and tire pressure fluctuations at these pressures and temperatures encountered in aviation are immense with regular air.
So, in race cars, or fast cars in Europe, nitrogen in the tires makes perfect sense to me. I uses to get my tires so hot, you would NOT want to touch the sidewalls for long, definitely uncomfortable.
If youfill your tires with nitrogen, the air pressure increase from this heat is a non-event. Nitrogen will start to expand at much higher temps as are practical in automotive/trailer use.
I do not think it's a necessity for US street use.
My friend who races carts use nitrogen in the little gumball tires, they are very small and get very hot, so pressures would be very inconsistent with regular air.

I don't know about nitrogen in my tires but sometimes the inside of my car seems to fill with methane.

biggerbadbrad · 11-11-2003, 12:36 AM

I prefer to fill my tires with hydrogen. Well, until I hit that last pot hole, that is.

Sorry Uwe,
Someone is misleading you.
"The coefficient of volume expansion for a gas under constant pressure is nearly the same for all gases and temperatures and is equal to 0.00367 for 1 deg C." from
the Handbook of Chemistry and Physics, 59th ed. pg F-122.
Also known as the ideal gas law: PV=nRT

( it even applies to the expansion of methane inside the driver's compartment)

For correctly answering the question you win a genuine "AIRSTREAM" Embossed Plastic Pocket Pencil Protector with a picture of an Airstream being pulled by a bicycle.

Now, for the bonus question, .....

What would be the pressure in the bicycle's tires be if all of the heat generated by braking is transmitted to the tires after negotiating Wolf Creek Pass and the Airstream and bicycle are safely brought to a stop in downtown Pagosa Springs?

Note: No mass change from the bicyclist is assumed, as modern fabrics will contain all bodily fluids and solids expelled as the cyclist negotiates the first switchback.
