Can someone identify these wheels?

Does anyone know what kind of wheels these are? I think I'm in love with these things, they're beautiful.

The truck belongs/belonged to Pepehn. I would pm him but apparently he hasn't been on since 2009 :/

I believe those are Denali wheels, couldn't tell you the year though.

Those are 2001-2006 GMC Denali/Denali XL/Sierra Denali/C3 17" wheels.
