I did look through most of the posts here and can't seem to find a complete picture of what I'd like to do. So I figured I'd ask here. Oh, before I get started, I have the original staggered 14" steel wheels and correct covers if anyone needs them. So, I'm looking to stay 15" but would like a fat-* tire in the rear. Everyone seems to be running the 275/60r15's on 15x8 or 15x10 wheels but no mention of backspacing. I found some 15x10 with 4.25BS, not sure if they will clear or can I make them work with a spacer? I'm clueless on these. Also want to go 15x7 or 15x8 in front maybe a 235 or 255?? Heck, if anyone has a bad* setup, show me a photo and your specs! I'll credit you in the citation section of my build book, lol. Thank you all for having me, let me know what you think.
