And this is why 17's and 18's make so much sense. With a 17x8" and 5.25" of backspace most BBP A-bodies could run a 245/45/17 all the way around with pretty much no modifications at all. Cars with 8 3/4's and BBP axles probably wouldn't even need a spacer in the back, 8.25 and 7.25" cars would though. And a 245/45/17 is a pretty popular size, so, lots of tire options. That's probably exactly what I'll do with my '71 GT, if I can stick with the plan and NOT do a 1/2" spring offset on that one.
