After your track session let several pounds of air out (~ 5) since they air will be heated/rarefied and you'll have elevated pressures that will promote premature wearing of the center of the tire with normal street use.

Enjoy!
47 cold? Please tell me that is a typo...

EDIT: Looks like that wasn't a typo. Seriously bad advice and dangerous to run pressures that high. 47 cold for a PS2 would wind up around mid-50s psi hot.
