So I'm not Duc, but I do have a set of these tires. I gotta say he influenced me and I got the same setup in the same size, 325/65R18. They are really wide tires.
They are really quiet. Not just for a mud tire, as in I don't notice tire noise at all. They also have phenomenal traction in the snow. Not so much on the ice though, on ice they're a little slickery But that was to be expected with a mus tire.
I did have some trouble balancing them. Discount tire tried a couple times and failed, so I went and got some balancing beads. 8 oz each tire. It helped, though they are still not perfect. I can feel a slight vibration right around 55 mph. I think with more of the balancing beads it would've worked much better.
