Quick tire pressure question

422 Views 1 Reply 2 Participants Last post by  KEVINS
When you guys measure tire pressure on slicks, do you do it immediately after a run, or before it when the tires are cooled off? I've been running 15-17 psi hot (right after a run) in my ET streets and want to try going a little lower as I hear 12-14 psi is the magic number for these. I just want to make sure I'm running the "coorect" 13 psi.

b4.. Traction for the launch is more important..

On our race truck we check it just before we enter the water box.
