For what it's worth here's a couple pics of my car. Not exactly the same as yours but pretty close. 235/60's up front and 275/60's out back. 15x7's w/ 4.24" back spacing on all 4 corners. When I burn these tires off the back I'm going with 325/50's on 10" wide rims. Lots of room back there. 295/50's would work on a 8-10" rim. A wider rim would make the tire look wider, but it would work either way, but I think 8" would be the bare minimum.
