I'm looking into upgrading my 3" and 31's w/ stock wheels to a 5" and 33's. My question is, i dont want to do too much trimming, and if possible would like to keep the stock flares (i dont mind cutting them but i dont want to remove them). My goal is to keep the tires from sticking out too far so anyone w/ actual experience in backspacing a 15x8" what is the closest i can go w/out rubbing? I searched some guys got away w/ 4.25 but i heard 4.75 would be alright as well, is that b/s? (what is stock 5.25?) Thanks for any info.
