275/60/15's on 15x7 cop wheels on a 71 Dart?

I'm curious if anyone is running 275/60/15 tires on 15x7 cop wheels (or some other wheel with the same backspacking and size) on the rear of a Swinger? Curious if there are any rubbing issues...

I have NOT done any kind of spring perch relocation or anything like that... it's got an A-Body 8.75" rear end with big bolt pattern axles.

Thanks
