I have had SIMILAR issues with mine, but I also discovered another issue in the process. I knew the falken were riding too rough and loud and took it back to the shop, they found a flat spot in the wheel that I need to get fixed, but I am truly wondering if this will solve the problem. I have not read this about these tires from other reviews, maybe something to do with the XF and the tires together? I only get it from about 50-80MPH, once I have the wheel fixed and can put some miles on, I will let you know what I find out.

But, starting at ~ 45 MPH I get a "thrum" with a 1 1/2 second period. What I mean is it goes "thrum...thrum...thrum...".
It DOES NOT change with speed.
It DOES NOT do it on all road surfaces.
It DOES NOT shake the steering wheel.
IT DOES NOT seem to be tire hum.
It feels like it might be coming from the rear.
I have had all 4 re-balanced. No change.
I will (finally) install the stabilizer in the morning to see if there is any change.
And I'll slip it into Neutral at 70 to see if there is any change too.
It's the strangest thing...
I respectfully wait for any help?
