the car currently sits on 275/40/20 NT-05 fronts and 315-35-20 NT-05R drag radials on the rear. this is probably the ABSOLUTE biggest you can run in our wheel wells. I'm actually currently awaiting coils so I can tighten down the dampening to keep the car from squatting and bottoming into the fenders. There's not even a fingers width of room tire-fender on all four corners.
