I spent many months researching and admiring many of your wheel/tires combinations and came to the conclusion -wheel and tire questions appear to be among the most discussed topics. So many questions about offset, bolt pattern, width, height, do they fit?? After looking on various sites on the web, I ran across the following format and I would like to propose we use the following too.

on my 10" rear wheels (aftermarket, not a widen factory) I went 5.7 backspace and wished I would of gone to a 6.0 I have plenty of room on the inside and very tight toward the outer quarter panel lip. Hope that helps, let me give you a word of wisdom, measure 3 times before you spend the money. Wheels are not cheap! Borrow as many different wheels from friends etc and try different ones for best references. I was lucky a friend brought over a front & one rear to measure from and still I wish I would of made a better choice in back spacing.
