6 1/8 BS and +30 OS

I thought the stock offset was +44 and the wheel width was 7.5". Given those numbers it will stick out an extra 1" or so:

need to know how wide the wheel is. if its an 8.5 or 9 wide it should work but you will need a leveling kit. I personally think the 5.5 BS wheels look best.

--A 5.5 BS would push the wheel out further than the 6.5 BS? The wheel I'm looking is a 20X9, either 5 3/4 BS with +18 OS or a 6 1/8 BS with +30 OS.
EDIT: I'm not sure the bolt spacing of the 5 3/4 BS will fit my truck, it's 5.5 whereas the 6 1/8 BS is 135...

Yes, the less backspacing (i.e. the more negative offset) will push the wheels out further.
If you have a 9" wheel with 4.5" backspacing, then the offset would be 0. As the backspacing increases, the mounting pad moves to the outboard side of the wheel and the offset increases as well. The stock Ford rims' mounting pad is closer to the outside of the wheel, ergo the +44mm offset. If you have backspacing that's less than half the wheel width, the offset is negative, that is, the mounting pad is more towards the inside of the wheel.
My wheels have a -12 offset, so they stick out a little bit:

Mine stick out about 2" more. The stock 18's are just about perfect flush with the fender flares. These sling a little dirt and crap on the side so I've been considering some mudflaps or bigger fender flares (spendy though).

Heres a good chart to keep. a 9" wheel with a -12 offset is 4.5" of BS
Im running a 20x9 with 4.5" of BS or -12 offset.... leveling kit and 305/55 TG's
