would these rims fit 255-60-15 and 215-65-15 ? also the springs will raise my rear end up maybe an inch or so there 5 leaf instead of 4 would 255-60-15 on rear work or would it look to jacked up i belive they are 15 x7 and they are supposed to be a upgrade rim that was offered then
It'll likely look jacked up. Your combination would have a one inch larger diameter tire in the rear. The wheels also need the correct backspacing to avoid tire and wheel interference problems. A 7-inch wide rim should generally have a 4-inch backspace.
You can play around with tire sizes and gear ratios, plus more information, in the spreadsheets here:
First, that's not the way to measure a rim, see attached image.
Second, you have 14x7 rims. If they are painted with a trim ring, they're probably off a 74+ Cougar, Torino, Granada or similar.
You can run a 255/60R15 on the rear without rubbing issues with a 15x7 rim with stock offset. You can run the same size tire on the front as well, but it may rub at full lock when entering a driveway.
