Well, I run indoor clay and the tire of choice is gold barcodes, pink suburbs, and I like soft panther switches myself and bobcat fronts (old tire of choice). When the track is holding a tad of. Moisture u run them scuffed in and when it dries out good we run slicks that have bn treated with compound of choice, during second to thired round of heats we run worn tires with bald centers with tread on outskirts of the tire. When the slicks are hooking up we normally run more treaded tire on the front so the car don't oversteer lol
