My initial thought was tire noise.....bc it gets louder the faster i go..... and ain't no way that can be normal in an expensive car like that...... it's very hard to explain...... it's a constant noise.... doesn't go louder then lower then louder....... **** is about to make me lose my sanity lol

I am getting the same humming noise at higher speed from the back. I have already got new rotors and pads on the car, so its either the wheel bearing or the run flat tires that are worn out unevenly from the inside. Any suggestions or thoughts ?
