    you should play with it when you get there inbetween passes, but with a 315 tire, you shouldnt have too terribly much of a problem with traction, thats a lot of tire.. are you spraying off the line?

    if you lower it too much then that big tire will be a lot of rolling resistance after you launch, i'd start runnin around 25 PSI and see what happens

      You definately don't want to go too low with that wide of a tire or the center will crease in a little and won't touch the ground. Is it a street tire or a drag radial? If it's a street tire, I wouldn't go any lower than 26 or 27. If it's a drag radial, maybe 21 or 22, definately no lower than 20.
