Not bad... too polished for me, but that's just personal tastes. Well, a nice offset for a 16x7.5 is around +20. That's the offset of the Keskin KT1 Klassiks that I want.
A +38 won't even fit without spacers. You'd need like 16mm spacers to clear the front struts I think. I'm no wheel/tire expert though, so hopefully someone will chime in and add to the discussion.
