My car is doing the EXACT same thing. I also have DWS tires on 162's. I did have the rear bearing replaced 2 years ago (at 70k miles) and that was a constant humming that was quite loud. I have had the tires replaced and road force balanced several times. It does seem more noticeable when the car is cold from sitting in the garage all night. I was toying with the idea that the drive shaft was slightly out of balance. Just spit balling.
