What would the optimum offset and wheel size be for a 235/45/17 BF Goodrich KDWS T/A and Eibach springs? I would like to use a 17x8 because the bead to bead on this particular tire seems wider than advertised. I have stock struts (not that it matters) and suspension. I want to make positive that I don't have any rubbing issues. Thanks for the help.
