Waaaay back in the very early 70s, I was running G60-14 (26.6" dia.) tires on the back of my '69 340 Swinger and D70-14 (24.9" dia.) on the front. Of course, you have to understand the correct stance back then was a little jacked up for weight transfer - kind of a "gasser" look.
The hot set-up back then was also air shocks to raise the back of the car - my Dart was up about maybe about 1.5" in back. I cranked my torsion bars up so the bottom of the car was level. With the smaller tires on the front it gave the image of slightly more front wheel opening above the tire. It was a good look back then and would definitely work with SS rear springs if you're going for the retro look. Maybe I'll do it again when I get my current Dart finished.
