I could run lower psi and get all the tire on the ground, but the hoosier DR's are rounded towards the edges. I have ran at 16 psi and as high as 38 psi, both felt like I was a little squirly at the top end. I didn't like skating around and my 60' times weren't any better. So I have stayed with 27.5 for DR's and 36 for stocks. Be Safe and Have fun.

Sidenote: this was with temps from the 50's to 70's. As it gets hotter I will see if this psi still works.
Just curious cruzinquick, what size Hoosier DR's are you running? I've got the 275/40/17's and was planning on starting out at around 28 to 30 psi if the mid-west event at US 41 don't get cancelled because of weather on the 12th.
