The car has every option BMW offers, DHP included if it matters. Dealership can't isolate it but does recognize the problem and has documented it with corporate. Doesn't feel its wheel bearings. I lean towards these Goodyear ROF's as the culprit. A Michelin guy myself. Anyone else with a G30 having this problem? It has 3,500 miles on it. Love the car otherwise.

I can second you with his, I have the same sound issue on my 540i xdrive, while driving over 60mph. I have a 20inch setup with extreme contact dws06, and have ran it with goodyears before. Dealer cannot isolate the problem as well.
