Hey all. I was just wondering if there's any place to buy nitrogen for tires just with a tire chuck, or if I have to get one of those high pressure cylinders and regulate it down. That is all. Thanks. (IMG:style_emoticons/default/beerchug.gif)

you need to originally mount the tires with nitrogen
the circle track guys believe that if a tire was ever mounted with air, it will never be 100%

they make purging machines you can buy to use after the tire is mounted to vacuum all atmosphere out and then refill with nitrogen for racing.

I've also been told that 6 complete fill and drains will work nearly as good as a purging station.

buy a big bottle/tank
they use different regulators than some other gasses.
figure about 250 for a tank and regulators plus the gas itself

fill/purge

and by the way
road racing guys don't have it much easier
it take 1.5 laps to get those tires warm enough and then they go away after about 6-10 laps when they overheat
(all phases/states in one session)
