After a little over a month of use on pavement, gravel, mud, rock, and rough trails I am very happy with the tires.
I just got back from a weekend at Piedmont, MO and we rode pavement and gravel to get to our trails, sometimes at 60 plus MPH and very challenging ungroomed trails and they handle everything with ease. I was a little concerned when we went from mud and hood deep water directly to rock crawling but I just stayed in the throttle when they slipped while wet and they heated up and just gripped the rock with no problem.
Other people at the ride were impressed with the performance of the Pioneer and the TSL tires. I think I might see a few rigs sporting them at next year's ride after I cleared every mud hole and many others had to pull cable.
