I experienced the same issue as you, but it didn't show until 15k miles. The response I got from the dealer was the tires were "feathered" and while I still have plenty of wear left on the tires at 22k miles the noisy ride is really irritating. I was pondering replacing them with other tires and after reading these postings I am definitely going that route.
