just got 07' crew cab 1500 ltz,6.0,max trailer,. put skyjacker leveling kit on and want new wheels,285-70-17,nitto's. would like 17-9" wheels with 4.5" backspacing so when i can afford a bigger lift (8-10") i won't have wheel to spindle contact issues. i am afraid these wheels may be too much. should i stay with 5" + backspacing?
