Have you seen the 8" wheel with the trim ring on? I'm pretty picky and the little gap that is there doesn't bother me a bit, but you may see it differently. What would bother me more is trying to run a wider tire on the back on a 7" rim which is going to make the back tires look different than the front do. I run 245/60 on 7" rims on front, 275/60 on 8" rims on back and the sidewalls look very similar front to back. Just something else to think about I guess.
