I have them, and they are great in the mud( not as good a super swampers) but they are better than super swampers because they don't wear like race car tires, and they are dead silent on-road. Well worth it for a DD.
If you are off-road more than 50% of the time, and don't mind quick tire wear get Super Swampers. They are the best by far off-road, but suck on road. I have the Toyo m/t because they handle good, are quiet, and Jeeps can get over 50k miles on them. Plus they dominate in mud. Had to pull my friend's 4runner with a/t tires out of the mud hole i made it through with no major loss of traction.
