Tire sizes

[strictlypersonl]

50/50 that 255-60 is going to rub on the front. I recommend the smaller 235-60s. The smaller tire is a better fit to the 7.5" rims too.

Bob,
Do you think they'd rub on the inside or outside, or both?

Eddie is running the same size tires on his street 427, which is why I figured I'd run the same (his car handles and rides like a dream). I'll ask him, but I don't think he did anything special to avoid rubbing. I know he had to replace the first set (which was a different size) as they did not work.

Thanks,
Evan

I see no reason to risk the 255s up front when the 235s are tried, tested, and true on the ERA cars for decades.

ERA 488 below for reference:
235/60 up front with the 15x7.5 wheels
255/60 in the back on the wider 15x9.5 wheels


ERA 472 also had the same wheel/tire size up front, but 295/50 in the rear:


That being said to the OP, every MFR of car and wheel has their own offsets and sizes to hit for optimal fit so follow what the MFR recommends.

It's still not clear to me where the 255s might rub in the front. Eddie had the flare behind the front wheels trimmed to be like the early cars, but it doesn't seem like the front tire would rub even without the flare trim?
