nitrogen

[Joe Helms]

I used nitrogen in the slicks this past weekend for the first time, and noticed took more effort to bring smoke off the tires in the box, is this characteristic of N in the tires? Anyone have similar experience? Otherwise worked really well, much more manageble in the heat! Joe Helms

Joe I spoke to the Hoosier rep earlier this year and he advised againt using nitrogen in the slicks and the reason being is that it will keep the temperature of the tires at a lower point and not allow them to hook as well. I am currently using nitrogen in my front tires and find that my front tire pressure is very stable.

Mark, I had heard similar comments, thought I would try anyway. On bias10.5/30s, track temp 130f and tires 180f had no problem with traction or consistency, in bracket setup. Main advantage was much easier heat management! Sidewalls show a little discoloration, though.. Joe.

Bringing this post to life again. Anybody have any thoughts on using nitrogen in a stocker. Is it worth the investment, since you check them everytime before you run anyway? Does it give any ET advantage?

i want to know if there's that much difference between 80% N and 95% N....and if there's that much difference, can you PROVE it?

helium makes better sense to me cuz 80% nitrogen is whats already in the air....

First, I am not for it or against it but it is the make up of the air we breathe is the big difference.
Its the moisture in the air that makes the pressure go up and down radically with heat or cooling in the tires.
With nitrogen there is almost no moisture as to bottle the Nitrogen it has been cooled to liquid which requires cooling it to if I remember correctly about -190 degrees C therefore there is basically no moisture in it.
Bottled nitrogen is made from air because there is so much in the air we breathe.
Helium is much more expensive and much lighter which would make it less stable with temp changes. It also leaks out much easier.
Just My 2 Cents

Helium wouldnt work in a tire well for a couple reasons. but it on top of that is a HUGE thermal dispersant.

If youve ever breathed helium ox mix in mixed gas diving....well itll litteraly suck the heat out of you from your lungs......unless its warmed, and youre in a hot water suit great way to go hypothermic in about 20 minutes flat.

oops, i forgot the "".......it was a joke (about the helium,EVERYBODY knows hydrogen is the hot ticket)

I have never seen that much variance in my tires, even on back to back runs, with just regular air . That is why I am asking the question. I can't see the logic in it, or the expense, but I am open to opinions.

Simple, nitrogen makes your tires run cooler. You will have too heat them longer to hold the heat this will = faster tire ware costing you more than the worth of buying nitrogen.
