I bought a set of 35x12.50's last summer. I love them. Cheaper than swampers of the same size. Mine are quiet, way quieter than my buddies Q78 swampers. Not as quiet as a all terrain, but I can only hear mine with the windows down. As far as how they work, mine got me through the same deep snow drifts with open axles that my buddies truck got through with his swampers and being locked up. What little I've tried in mud worked well, but I don't go looking for mud. They clean out easy with a blip of the throttle.
Plus since they are radials they ride nice and balance out with minimal wieght. I got mine at sam's club for $125 a tire. If you are on a budget and need a solid tire they are a good choice.
