Was at the track on the weekend and I'm just trying to find advice on what tire pressure might be good. I'm running Mickey Thompson ET Drag 22.0-8.0-15 and I was starting out at 11psi and getting 2.0 60" times. So I dropped it to 9.5psi and I hit 1.85 60"time which was my best ever. I making approx 270whp in a heavy car, but I was wondering if anyone has any advice with this size tire or if I should keep dropping the pressure or if 9.5psi is low enough. The tires looked flat at 9.5 psi, but I suppose after warming them the psi will rise a bit? Thanks

Edit: Just found a good post about tire pressure, reading through it, it appears that most people are running between 7-8psi, good thread though
