new wheel: 8.5", et 42, 255/35/18
and it spits out: "2mm MORE clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 14mm"

That calculator is flawed. It only calculates the wheel clearances and ignores tire sidewall clearances completely.
The only dimensions it's calculating for tires is the diameter and it's using that to calculate speedometer error.
