Great, now I'm going to have to figure out which backspacing to get. Time to do some reading. Then Im going to have to paint them as well. Oh the humanity!
If you go with the 15x7 with the 4-1/8" backspacing listed there, you will be close with a 255/60 and may need to trim the inside lip of the rear fenders by 1/8" or so.
Not hard to do, but a 245/ should fit just fine without trimming.
