Brain fart on my part, thanks for bringing me back on track .

And if you check out this TÜV approval document for BBS wheels (needed to legally have non standard wheels and tires in many EU countries) you will see that under the heading "Befestigungsmittel", there are 6 alternatives, both M12 and M14 for the same wheel (depending on which car it's to be fitted on).

So at least on those BBS rims it's possible to fit both M12 and M14 bolts

Also, the 255/275 sizes can be seen on the show car pictures, both on 19" and 18" equipped cars.

You're right, my bad

Those are low offsets?!

Both are 255F, 275R.

Not to bring tires back into the discussion but has it been confirmed the cars will ship with SuperSports?

Most likely (...or maybe Conti's or Pirelli's like the E9X).

Oh nice. Good stuff. Square 10" might just work with a subtle flattening of the fender.
