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. |

QUOTE(brant @ May 27 2004, 07:42 PM) Oh gosh I'm an idiot.. I forgot you were on slicks.. b I wouldn't say that. Slicks or DOT tires - it makes no big difference. I used to race on DOT tires, and I don't think I ever saw 10 psi increases. The pressure settings were higher though. I set pressures between 18 and 19 psi cold with the Hoosier slicks, and I used to start out with 28-30 cold using both Yoko or Hoosier DOT tires. The pressure increase was about the same. The people who get such large pressure changes have cars with front engines, either fwd or rwd. The lack of balance of those cars causes the tires at one end of the car to work much harder. Anybody driving a 914 who sees a 10psi increase is probably abusing their tires IMO. |
