although diameter of wheel has no effect on backspacing if you size the tires correctly (same as stock, upsizing like this: stock is 245/45/17, if you go to 18s its 245/40/18 to maintain same diameter)Realize that 56mm is for a 8.5 wide rim, a 56mm backset on a 10" rim is a deeper rim and will protrude in towards the motor side more. You may get away with 12mm deeper (or 1/2") before you start rubbing on things back there
Simple backspace formula is wheel width divided by 2 plus the offset plus 12mm (1/2") Figure every 6mm is 1/4" (or you can google 'mm to inch calculator')
