I rotated my tires and now they are noisy. I've considered rotating them back and then never rotating them again.
This happened when I rotated my original OEM tires the second time at around 20k miles. I had the tire rotated back and the noise was less. I never did rotate the tires again and would have gotten 50k miles on the set had it not been for a side wall problem on one tire. I think the side wall problem was due to hitting a curb. I replaced them with another OEM set and have rotated them several times with no noise problems at all. This second set of tires currently has about 25k miles on them and they are wearing well.
