When you take the oxygen out of the tire, you have no moisture, therefore the tire does not build up near the heat.
If you and I had the same weight units and the same tires and pressure, mine with nitrogen and yours with air, if we were to drive say 100 miles my tire temperature would be quite a bit less. How much I do not know.

WOW, this thread reminds me "Y2K", suddenly everybody became an expert, and in the end, none of them knew anything.

Why don't we switch this to something we can all agree on, which motor oil fights sludge better, Castrol or Penzoil?

(no offense to anyone, been a long day, put this one to bed).

=============================================
That pretty much says it all.
I'll stick with my free air and 78% nitrogen.

Uh-oh, didn't we just have this discussion in another thread that Kim had to close ?? And I think I was a contributing factor in that thread, so I am going to keep my hands off of the keyboard any further on this thread.

Since the original topic of this thread was "topping off the tire pressure", I hesitate to carry it further, but Jack, the one way to put this issue to rest is, show us the stats. Your response above ("How much, I do not know"), indicates you are going on heresay. If you can show some numbers, please start a new thread. We'd love to see some solid proof.

To show that proof you would have to have identical units other than the choice of air fill running an identical route. Hard to do.
But you won't be happy otherwise.
There are hundreds of trucking companies and some bus companies realizing reduced tire costs that are running nitrogen.
I will leave it at that.
PS...yes the topic is 'topping it off'. Like I said, in three years I lost exactly one PSI using nitrogen. In the two years prior I was adding about 5 five PSI a year.

What "Straight Dope" has to say

The Straight Dope: Is it better to fill your tires with nitrogen instead of air?

As an aviator for 33 years, this answer seems right on the money to me.

Well Herk...right on the money or not, it will not end the debate. I just can't see paying more than I already have to (when I do have to pay for it at a station). Plus, I've only seen a couple of places that even offer it. If there were substantial proof that it really did any practical good, and was more readily available, I'd be all over it.

Jack..I suppose the bottom line is, if it works for you, great. As long as we can all get out and have a great time camping, that's what is really important!

Ed,
I think you misread the link.
I am an "air is OK for land use tires" guy and the link has the same opinion.
There are reasons for nitrogen in military and commercial aviation tires. One of them is when the tires pop from the heat of a wheel well fire, the nitrogen will not support combustion and can actually extinguish the fire if the wheel well doors are closed. Most civil aviation tires use regular air.

Since tire pressures are checked and "topped off" if needed on every preflight it really does not matter what is in them. Most FBO's just use an air compressor to fill and maintain the tires.

I like the Argon idea. Hydrogen would be bad, even though a case could be made for lightening the trailer's GVW.
Opinions are universal and are issued "one each" to everybody.
Everyone is entitled to their own opinion; just not their own facts.
