Biggest Tire In Stock Wheel Well?

Using the .80 spring relocation kit on my '65 Valiant I got 28x11x15 ET Streets mounted on 15x9 Center Line auto drags under it. I had to roll the inside of the fender lip in on each side and if I filled the trunk slam up with groceries and my son rode in the back seat, the tires would scrub on a hard bump, but very seldom even then. I was running the 002 and 003 SS springs. That was a really quick street car, too.
