0 offset will yeild 3.5" back spacing on the 7" wide ones and 4" BS on the 8" wide ones. so... They sound like they should work fine. I run the 3.5" BS wheels all around and they fit great. The rears can obviously accept a larger tire which should be fine as it will set in towards the frame more on the 4" BS rear wheels. Just don't go larger than a 245/45/17 in rear to be safe. 275/40/17 *might* fit in back, but you better mount them up at a place that will exchange that size for a smaller tire in case they rub inside against the frame.
Hope this helps,
