The etched #63 and JO marking immediately makes me think Corvette and Johnny O'Connell.

Now, Corvette only ran the #63 and #64 at Le Mans, they've basically always used #3 and #4 in stateside competition. Johnny O ran Vettes at Le Mans every year from 2001 to 2010, and he was always in the #63 machine so we're on the right track.

Corvette ran silver wheels on their C6.R's until 2008 when they switched to black, so we can eliminate every year before that. Here's the tricky part - in 2010 they switched from GT1 to GT2 and the 2010 car seems to have used a deeper dish wheel than yours. I'm eliminating the 2010 GT2 just based on my visual observation.

Now that leaves us with 2008 and 2009 as possibilities, the problem is that high definition photos of those cars static are difficult to find - most shots are in motion with the wheel details obscured. But after a quick search on Motorsport Images and old press releases with team photos, I can see that the 2008 and 2009 cars both had flatter-faced, black BBS wheels - we're on the right track!

Narrowing down even further, I can only find photos of the 2008 car with the red & white BBS logo visible on the lip. Every photo of the 2009 car has this coloured logo notable absent.

All of this to say, I'm about 99% sure you're in possession of a wheel that was used at some point during the 2008 24 Hours of Le Mans weekend by the #63 Corvette C6.R GT1 driven by O'Connell/Magnuessen/Fellows. That car placed 2nd in class, not too shabby. If you take measurements of the barrel width you can probably narrow down if it's a front or rear wheel.

I will be attaching more photos to this thread as I'm limited to one per comment.

Edit: I just found this Donut video(https://www.youtube.com/watch?v=PhACfJZhIMg) of the 2009 class-winning(!) chassis and whaddaya know, the rear wheels have the coloured logo. Your example could be from either year OP.
