Help to diagnose front end noise.

[javis20]

Car is a 2011 BMW Z4 E89 85K miles
Oscillating, speed dependent noise, from front end. Car is coasting down a newly paved hill in neutral. First part of video is "as recorded" the second part is the same video with engine noise removed via Izotope RX11. Noise is most pronounced in both video parts near the end, while braking.
Background...
1. Front left shock is leaking. and need replaced. (I don't think this would cause this issue.)
2. Three of my wheels were diagnosed as bent. One, that was very bent, was replaced with a new BMW wheel. The other two were diagnosed as slightly bent. They were taken to an alloy wheel specialist and straightened, cleaned and powder coated.

Any thoughts as to what is causing this annoying issue? Video and sound file attached.

Could be a deformed tyre …

Have to agree, it does sound like a miss shaped tyre.

The bent wheel has been there the full life of the tire. Tire has been on the bent wheel for about 25k miles. Last week the wheel was repaired, but still have a problem. Possible the bent wheel caused irregular wear or damage to the tire over 25k miles.

When I bent two of my wheels in a coal mine (pothole) last spring they made that noise..fwiw

I’ve had a noise that started as a sush, sush noise and now is a womp, womp noise. Saw a couple of YouTube videos tonight about tyres being cupped. Went out and ran my hand around the inside tread on the front offside tyre and part of it I can feel the ups and downs. With the roof up that’s where the sound seems to be coming from. Might be the same with yours.
