Wheel with shallow holes on 300TE

[MCallahan]

OK, so when I got my 92 300TE, I noticed the right rear wheel had the lugs protruding past the face. No big deal, figured it was the wrong lugs. Had to pul them to get to my toasted rear wheel bearing today and decided to swap with the correct lugs on my parts car. The lugs on the parts car are identical. After checking a couple of wheels, I looked at the wheel itself and the pockets for the lugs are shallower than any other wheels I have by about 3/8" (9mm). Any idea what this wheel is from and does anybody need it? I have six more between the parts car and spares for the parts car and my wagon. I'm just going to pull it and have the new tire swapped over.

Speaking of wheel bearings, looks like 143,000 miles is the engineered limit for Mercedes wheel bearings. I just did the fronts last week because I saw grease on the center cap of the driver side front wheel. Now the right rear is gone. Noticed it making noise, so jacked it up and gave that wheel a wiggle... rattle, rattle.
