O.Z. discontinued that wheel a long time ago...
There are a few options out there that are very similar and would make for a really nice set...
We can also get them in 14" up to 24" diameters, and 6" all the way up to 16" widths... 3-Piece Forged, Forged Monoblock and Forged 2-piece are available in any configuration and finish.
PM for pricing... Here is an example of one of the wheels...
