More data to chew on. Summit Point W.Va., Jefferson circuit is short (about a mile). Pretty hard to get the tires warmed up. I started the day (with about 65 degree air/track temps) at 30f and 32 rear. Still felt pretty slippery. I held off on lowering pressure cuz the old timers said the track would get stickier after each session due to sun warming up the surface and from people laying rubber in the race lane. It got a bit better in the second and third sessions. After the noon break I was thinking the tires still felt like they weren't holding like my Q2's did, so I dropped a few psi out of the front. Big improvement. I've seen tons of veterans say Mich. PP2CT's need to be run at about 28 cold to work. I thought that was wicked low, but turns out it was dead on.
