Tires are noticeably noisier (like most winter tires), but this whine seems distinct from that. And like I mentioned, the whine immediately went away if I went off-throttle or put it in neutral.

Thanks, I was just curious is you had the same tires as the OP to see if there was any correlation.

Have you also tried swapping the tyres from side to side? Uneven wear patterns and the start of cupping of the tread can cause resonance at some speeds (it could well come back at twice the speed that it currently occurs at).

A side-to-side swap can alter the noise volume or how it changes with throttle position, as the slightly worn tread blocks will be pressed to the road differently.

Not sure if your sound matches this at all but he has a video of the sounds from the outside as well as inside and it seems to be consistent with a certain speed as well. Could very well be something to do with your drive shaft.

Ive got Pzeros. less than 2k miles. And two alignments now. I dont think its tires. If I had to guess, its one of these things.

drive shaft
diff
electronic feedback of some sort
maybe fuel pump

Or just a normal characteristic of the car that only you and I have caught on to yet. Im praying its that! Or active sound.

Another thing I noticed. The radiator fan spins down when I come to a stop. The spin down of the fan when I come to a stop sounds pretty simular to the sound we are hearing. I wondered if the radiator fan was boosting itself when on light throttle between those speeds. But the sound sure does seem to be coming from right behind me so I dont think its that.

But its driving me nuts not knowing what it is. But I sure do feel better knowing Im not the only one who hears it.

Maybe it’s humming because it doesn’t know the words…

Ok I’m leaving I’m sorry. That was my dad joke for the day 😁
