I'm running my first DE w/my 996C2 this week-end at Pocono. When I ran DE's w/my 951 on MPSC's i looked to not exceed 40psi hot. For this week-end I'll be running Michelin Pilot Sport Rib N1's (225/40 & 285/30-18's) on Carrera 5-spoke lite alloys. What pressures are recommended for these street tires at the track hot/cold?
