Recently I noticed when I have the windows down, there is a "womp womp" noise (I think this is how this noise is usually described) coming from either front our rear (or both) tires on the driver side. I had that before with another car and the noise was coming from the brakes. This time I can clearly hear that it is a tire noise. I inspected both tires and I can't see any visible sign for an issue. Any ideas what this sound could be? As reminder: this is a 2019 S90 which was sitting on the lot for about 1 year before I bought it. I had it after 1000 miles back to the dealership and they replaced all 4 rotors. I started to notice this noise after I received the car back. Thank you in advance for your help.
