wheel backspacing

[KingKJ]

What is the stock backspacing on the stock wheels for the liberty? Also if anyone has tried to fit stock wheels from a liberty onto a XJ I'd like that input as well, I'm trying to figure out if I'll be able to salvage my newish tires from the liberty and put them onto my next rig(most likely XJ) without worrying about backspacing, From what i've found xj's have 5.25 backspacing with 15x7 rim, I'm wondering how would the liberty's backspacing and 16x___ rim compare, I only know rim size for liberties, unsure about width and backspacing.
