So is anyone using nitrogen in their tires? According to the local news, it costs about $5 per tire to fill them with nitrogen instead of good old fashioned air.

Oh man not this again....

It's been a while since there's been a nitrogen thread, hasn't there?

I have regualar air in my tires now, but I prefer nitrogen. Logic being that I'd rather have the nitrogen then the wet, oily and dirty air that the tire shop's air compressor might have in it. In this truck, though, the rims can explode, catch-fire and vomit molten allow all over themselves for all I care...

 

OK, OK, that's one that I missed.

How about helium? Shall we discuss how much lighter our trucks are with helium in the tires and how much better the 2wd trucks hook up at the track with helium in just the front tires?

 

Discerning DTR drivers prefer argon. It's very expensive and therefore better than what anyone else is using.

Just because someone whats to sell you something doesn't make it a good thing to buy. Nitrogen is a waste of money. All it is is sales hype.

 

It would be simpler to just let 40 pounds of air out of each tire and you would take off a total of 160 pounds off your truck or 240 pounds if you have a dually.
Think how much an 18 wheeler could save.

I had a guy arguing with me because he said there is no way I could carry my Co2 tank with one hand when I told him it had 700 pounds of Co2 in it.




LSR cars all use nitrogen in their tires because it does not expand.

 

So you think that a full tank weighs the same as an empty tank?

 

I run nitrogen in my hemi, but then again I'm trying anything to gain fuel mileage. Although I never noticed any gains, Its to handle better around turns and such.

 

Of course not, that is how it is invoiced.
He was confusing PSI with the actual weight of the liquid.
My 20# tank holds 20# of Co2 plus the weight of the tank.
I have recharged many of my own bottles throughout the years.
Not 700 pounds.
Even air has weight.

So whats the advantage again?

 

No real advantage I see. Air is ~78% nitrogen anyway.
We in the Bat Cave use nitrogen to displace moisture. Since a nitrogen filled LRU has no oxygen present, there can be no corrosion.
As to helium, we use it as a coolant in our cyrogenic coolers. They chill to ~70*K (~ 380 below zero F). Helium, being as "light" as it is is a real bear to keep contained. We have to recharge our coolers every 2 years or so due to leakage. Nothing like a 675 psig static pressure.

Shortround out

 

Shortround,
a nifty little fact about Helium. 1 liter of liquid helium expands to over 800 liters of helium gas. I learned this while working with MRI machines. I have to provide the quench vents for these machines and when a cryochiller goes down and the magnet "quenches" or becomes superconductive, 800 liters of liquid helium boils off INSTANTANEOUSLY.

I saw a roof that was 60'x30' get lifted and deposited 35 feet away when one went off......... That had to be one heck of a WHOOOOSH!!! Good thing it happened at nite while no one was there...

I use Nitrogen in my tires too, but it comes contaminated with 20.8% Oxygen and a smidge of Argon...

You know that there isn't any water in there to rot and rust your tires.

And they'll last longer going around Talledega at 230 MPH, but I don't think that's really relevant for us truck types.

 

Maybe not for your wimpy little 1st gen but I'm buidling mine to outrun Jr. and Gordon.
