Just trying to clarify and perhaps looking for suggestions. I'm building up some 819 disc rims to King hubs for my trailbike. I think I remember hearing/reading that you can run non UST tires in the UST rims with no problems. I'll most likely be using Stans fluid anyway. Is this correct? I currently like Conti Vert Pros, NBX 2.3s, WTB Trailbears and Mutanoraptors with tubes. Should I/can I continue to use these tires or do I have to get the UST versions that are available? I'll most likely get a Conti Vert Pro UST tire for the front, but I'm not sure what to do with the rear. Suggestions? It's rocky, technical riding here in the east coast. Does Maxxis make something for me in a 2.3 or so?
