I mounted a pair of these tubeless on a UST Shimano rim with Stans. They were quite easy to get on and, as mentioned before, was quite simple with a compressor to kick the beads out (not with 3 different floor pumps...).
However, these have been tough to hold air. After setting them up and riding about 40 miles (with lots of pumping, rotating, shaking, spinning etc.) i added another dose of Stans. I sprayed them down with water a few times and you can see hundreds of pinholes in the sidewall foaming out Stans / water. It Does appear to be working but i now have about 100 miles and they still have a hard time holding air for an entire ride. Just beware. They are not UST so i don't think there is any recourse for returning the tires due to this issue. Other people have had good luck, so possibly the QC of these tires off the assembly line.
While riding, these have been pretty good, not the most aggressive tire but have been okay in sand to light mud. I have ridden more convincing tires but if these hold steady pressure for an entire ride i could give a more honest rolling impression.
