I pulled out one of my 18's - gray-silver, whatever.
On the back, there's a "GM" on one of the spokes. If the valve stem was at midnight, this would be on the spoke at 4:00.
Between the lug nut holes on the back of the wheel:
A sun looking thing with an 04 in it (year made?), and the sun has 10 marks around a 12 spoke sun (probably October 04)
Another part of the back of the wheel has the number 181410 with USA WTZ and a 4 in a circle.
Other markings: PNH in a oval with T-DOT and AA-356 under that. Another part has 958 with 4346 below that.
Last, 18X8.5JX56.
That's all the markings - with the exception of the GM, all are cast. The GM mark is stamped in.
Took a quick pic too:
Hope that helps.
Gregg.

Thanks guys. It was no trouble. I bought those wheels with the idea of having them as cores when I get a chromed set. So it was in a box handy to look at and to photograph. The weights on that wheel are quite a bit, aren't they? There's no tire on it now, but I would think it would be the tire that did that, not the wheel. Fortunately, none of the wheels on my C6 have that much weight!
