Just linking the tool I used:
Use our wheel offset calculator to visualize the new tire position when changing wheel and tire sizes. Convert wheel offset and backspacing to calculate the correct setup for your vehicle.
tiresize.com
I like it because it actually overlays the original and new options over each other so you get a better visual of stick-outage and suspension intrusion. Here's a snapshot of my results:
The inside is about half an inch further away, and the outside sticks a decent amount out further for that wide stance I wanted. I did have to compensate the camber up front and knock it down to more like 1 degree to 0.7 degrees, otherwise it was only riding on a thin patch during normal driving.
I kept the 5x110 hubs and bought 5x4.5 adapters on Amazon that were 25mm thick, so I just sized them as normal spacers. The tool above doesn't factor in wheel width, but as long as you stay within the width that the tire manufacturer recommends for the chosen tire size, you shouldn't have any issues since the wheel won't stick out past the tire, and the Goblin's suspension geometry won't intrude on that sort of thing. E.g., my wheel is 8 inches wide, within Falken's recommendation of 7.5 to 9 inches for the 245/45-17 RT615K+.
Here's how they fit IRL:
