Back spacing and off set

whats the minimun offset or the minimun backspacing you can use on 22x9.5 for a new model gmc pickup. and rolling the fender lips would not be a prob if i had too.

5.5 backspace minimum more would be better especially with a body drop.

my bad yall i just found out the wheels are 22x10 with 6.5 backsacing will that work???

come on some body help me out!
