A great all rounder, very similar tread pattern & depth to the old Michelin Mud the green ones!
Fast in the dry and good grip on wet grass, mud, soft spongey goo, etc
I have run these down to 35 psi on soft, wet courses with minimal pinch-flat risk, though I'm not sure that it was any quicker than 50psi would have been...
As for 85psi, I have used them at that on the road a few times, when I couldn't be bothered to swap wheels for a short ride & they were fine.
