I have plenty of room to spare from the inside of the tire to the inside tub. It will go all the way down just can't go too low while driving because it starts tearing up the side wall of the tire on that bolt.
The front is really limited to the inner fender, if it's unmodified without a pocket for the wheel and tire to tuck up into. The inner fender will rest on top of my 26-inch tall tire when my front air springs are aired down.

For the rear, I had to raise my bed 1-inch and run a sheetmetal Ford 9-inch and the top of the center of the housing still would contact the bottom of bedwood. I put an access door for my rearend filler and some electrical relays/fuel pump I installed there. Some people fabricate and bed-width hump to allow the rearend housing to travel past the bed floor.

As far as the backspacing on your wheel/tire combo, you really have to measure carefully, taking into account the tire section (not just the advertised tread width).Here is my bed to accommodate my chassis:
