I have a 62 step side with 17X8 wheels with the standard back spacing for that wheel. 4.5 sounds correct but I can not be sure (I can find out if you would like). I have 275 in front and in the rear. I have a 5 inch drop in the rear and they fit. With a 3 inch drop in the rear you should be fine. I might have rolled the lip of the rear fender a little to get them to fit.
