I did the 3/4" relocate. However when I went to buy tires I couldn't find anything wider than a 255 for a 16" wheel. Not an issue with 17" and others. So, now I've got extra space I'm not using (for now). I could easily fit a 275 with a little more backspacing. Course, my rear is a little narrower than stock too but I'd have to measure it because I don't recall the dimensions we settled on. I had Dr.Diff do it. I bet you could make it work without any mods at all.
