IME I lost more beads w/8's than I have with 10's.
The 10" wheel and a 2-2.5" back spacing will help to widen your track width, and to put your center of gravity closer to stock than the narrower 8's or w/a 4" backspacing. With the amount of lift you have you shouldn't have a rubbing issue, everyone I wheel with runs that little of BS w/that width of rim.
