OK, all you big time racers out there, what is the correct procedure to purge air out of a tire before filling it with nitrogen?
The reason I ask is that any moisture mixed with nitrogen will create nitric acid, or some such vile stuff, if I remember correctly. What about using air tools? Looks like a job for rubber gloves. |

andy,
I've always heard this is legit... actually I've already met with a gas outfitter and put him on the hunt for the remaining parts I need to finish out my conversion to nitrogen... the benefit is that in a lapping session, your tire pressures don't change as radically as they do with air... ie: if I start the session at 26lbs, I can finish the 30minute session with less than (hopefully) the 35lbs I have experienced in the past.... Randal, from my research (and not actual experience), I understand that just removing the core and letting the air out is inadequate... you have to mount the tire from the beginning with nitrogen... I hear this is a pain in the #$%, to haul your bottle down to your favorite tire shop with you.... I've been told by multiple sources that if you take a pre-mounted or used tire and try to purge it that there is still condensation and that it doesn't work... your mileage may vary.. my new car will be set up this way though... brant |
