Eagle 225 wheel / tire size question

I have a 1968 C10 with about a 4" front drop and 73-87 front swap if that matters. Early rear end. 55.5 plate to plate.

Looking at 20" Eagle 225s. They offer a 20x8.5" with -5, -8, or +21mm offset.

I understand the -5mm wheel to have 4.5 backspacing. If it was 0 offset, the wheel would be centered, at 4.25" correct? So, the -8mm offset would have about 4.635 " backspace (?)

Tire size suggestions for the ole stepper?

+21mm would be ~3.25" backspace? Am I understanding this correctly? Thanks.

Re: Eagle 225 wheel / tire size question

More offset gives you more backspacing, a positive offset wheel has greater backspace and less lip on the front of the wheel, and vice versa, a negative offset wheel has less backspace and a deeper lip at the front of the wheel. Someone correct me if I'm wrong please.
