Alright guys it's almost tax season which means I finally can get new tires. Yay. Ok to my question I have an 04 with a 4" fabtech shortarm that was on it when I bought it. I want to run 35's and if I can get wider then a 12.5 that would be awesome. I think I'm gonna go with 17 " wheels cause there are so many more tire choices plus I think the tires will be a little cheaper that way. What am I gonna have to do to make this work I am getting a mud terrain b/c this is a weekend driver and I do wheel it quite a bit. I don't know what backspace I need and I'm not sure if I will have to put on spring spacers or not thanks for the help.
