Winter - stone cold pressure is 34 PSI FRONT AND REAR. In winter driving I generally pick up 2-3 psi when the tires warm up.

TRACK - stone cold is 30 front 28 rear. The tires pick up about 8 psi after a few laps on the track. Sometimes I start at 28 front 26 rear on really hot days. I can't always get away with this because the nannies kick in if the tire pressure is too low to begin with.

Again - winter tires are a square setup and the track ties and wheels are staggered. Both sets are 18" compared to the staggered 19's for summer OEMs.
