Believe it or not they are quieter than my Hankooks which weren't very loud at all compared to most M/Ts. My dad has a pair of 35" KM2s on a 4" lifted F250. He's got about 10k miles on them and they don't look like they've lost any tread yet. I know some others have these tires and they may be able to comment farther on their performance. They are a more comfortable ride and quieter than the Hankooks.
I've actually heard louder A/Ts. In short I love em already.

Sorry I didn't get a picture of the tread pattern Knap. I'll get one on tomorrow night.
