If any of your tires were cupped, and you rotated them to the back that may cause an issue. I have noticed that on these vehicles if there is any issues with tires, the ones on the back tend to make more noise inside the vehicle than the fronts. It could also justbe that as the tires where the do get louder, however in your case, that shouldn't happen since you only have 11000 miles on your compass.
