Somewhere between a normal road tyre and a r888 style trackday tyre.
Lost of interesting info on the Yoko website but essentially they have 8mm of tread and the compound doesn't wear as fast as a trackday tyre because they don't lose rubber as easily.
But they do get very sticky if you warm them up properly and they don't try to kill you so much when you hit standing water.
A compromise essentially but a pretty good one
