After months of searching for a black alloy rims that would fit without any spacers, I gave up and just purchased the silver polished Level 8 Tracker rims. They were available in black several years ago and sourced on several builds here on mud including Bean's
here.
The silver ones are probably going to be gone soon since the rim has been completely discontinued. They are currently available at several online retailers but seem to be going fast - I purchased mine on Ebay. Since I was looking for black rims, I had them powder coated locally and just got them mounted yesterday.
I can confirm they fit perfectly without spacers and provide about 1/4 - 1/2" of space to TRE's, no rubbing at all. On another note, my old tires looked like they were in great shape - almost "new-like" tread on them but the tire shop confirmed they were sixteen years old! YIKES! The ride is so much nicer on the KO2's so I'm assuming those old tires were rock hard- check your tire manufacturer dates!
