On my 67 I have 245/45/r17s all the way around, same wheel specs. It’s fairly low and only has a minor rub when turning and in bump at the same time. But I also run over 0.5* of negative camber.
A problem that I recently noticed is that it’s getting a bit tougher to find good performance tires in that size. I’m currently running BFG Sport Comp 2s, but they have been discontinued
I’m thinkin for my next set(hopefully with 275s out back) I’ll snag some NT555s.
I’ve also had a set of Firestone Firehawk Indy 500s, I liked em well enough, but I try to buy American made stuff.
