You know the 85psi Max on the tire is the actual max pressure allowed by the manufacturer? For seating the bead only, in most cases... If a tire won't seat at "Max" pressure, use some lube.
I suspect the tire is stuffed if it was previously thumping, there are some snapped cords inside the casing, especially now after being over inflated. I have a brand new Schwalbe Supermoto X that simply won't seat properly, the casing is distorted, and I will replace it.
