6mm offset (positive) sounds like too much to me. I'd sure like to see a picture of that.
That would work out like this:
Tire Width | Offset
335mm ...... 31mm
325mm ...... 26mm
315mm ...... 21mm
305mm ...... 16mm
295mm ...... 11mm
285mm ...... 6mm
275mm ...... 1mm
I'm leaning towards this
Tire Width | Offset
335mm ...... 22mm
325mm ...... 17mm
315mm ...... 12mm
305mm ...... 7mm
295mm ...... 2mm
285mm ...... -3mm
275mm ...... -8mm
Or this
Tire Width | Offset
335mm ...... 25mm
325mm ...... 20mm
315mm ...... 15mm
305mm ...... 10mm
295mm ...... 5mm
285mm ...... zero
275mm ...... -5mm
Its obvious in the picture of 6018 it needs to be recessed a bit more (its a 325mm tire with 12mm offset). It would be nice to have Jim's offset as a data point. Although it calculates to 19mm based on backspacing, I'd guess its probably 22mm.
I can't believe Mr. Foose chose an 11" wide wheel for a 285mm tire, too wide, the sidewall will be canted inward.
