Thank you:sombrero: They are smooth enough for a E rated tire and quiet. I have had them out in some very muddy trails during a rain storm and they performed great, even on steep inclines/declines. They self clean very well.
I will be going out to the Mojave Desert next weekend for a test out in the sand and rocks. I expect them to do very well. Oh, and for what it is worth, I do not air down unless I am going on loose sand, but given the strength and thickness of the sidewalls, I do not think that these tires would bulge too much. Stay tuned!
Here are a few of the grades I went up/down when they were muddy. These photos where obviously taken when it was dry. The area is RRowher Flats in LA County, by Saugus.
