They're very quiet, John's been very happy with them. We can't really comment on wear, given that he's only put 5,000 miles or so on them, but they do look pretty decent, given the way he tends to drive. As for drawbacks, they're don't have the most aggressive tread pattern in the world, so they probably aren't the best choice for mudding or swamp rolling, but they are very well balanced for most off-roading conditions while providing a good street ride.
