I couldn't find it on my rim, either. I have only had one off, so far, but will be replacing all my bearings and seals in a couple of months. Maybe I can find it then. I didn't like the blacked out aluminum wheels when I bought mine. The dealer swapped them for the wheels I did like because another buyer at the time had the opposite wheel taste. I'll be watching... Not sure what company(s) makes aluminum wheels for RVs... I'd like to upgrade my tires, too.
