If you were coming from a different tire i would say its just the tires, they are reviewed as being noisy from tirerack:I replaced with the same tires BF Goodrich G force comp 2, 215 45-17. about 10,000 miles on them and loud with windows up or down. I hear it with radio on not too loud. I'm a piano tuner, so I don't rock out any more. The noise is louder than the engine until I get over 3,000 rpm. The thing is they were not loud at all when I bought them. Just got an alignment yesterday and toe was only a little out. Getting rotation today. I'm pretty sure it's only on the front.
The shop that rotated his tires diagnosed front wheel bearings being bad.If your toe was off, and started wearing the tire unevenly, correcting the alignment will not eliminate the noise. The tires have already been "damaged". Rotate them to the back, as others have suggested.
