am i understanding this correctly?

(A) 20x9, -12 offset, 4.5" backspace
(B) 20x9, -12 offset, 5.5" backspace

Wheel B would stick past the fenders less than wheel A due to the backspace, correct?

I've tried to find a picture of wheel spec B on an F150 but haven't been able to find anything that specific.

If the backspacing is correct then the offset is wrong on wheel be. Wheel B should have a +12 offset.

But yes wheel B will be tucked in more than wheel A.

The 5.5 you are seeing on there isn't the backspacing. That's the lug pattern 6x139.7mm = 6x5.5 inches

If they have a -12 offset then they have 4.5" backspacing.
