Terrible noise from the wheels.
The noise sounds like a resonating sound in the car. It hears very clearly in 35 mph. With 85 mph on the freeway, it is really disturbing. It can be heard faintly from the 5 mph you drive on gravel. The noise is even with winter tires. I have AIRMATIC and I wonder if it can be linked to the AIRMATIC.
The car is an S205, 250 Bluetec, 4WD. Built in Germany in November 2014. The tires are 225/50 -17. The rims are original. Reduces the air pressure in the tires, reduces the noise.
The workshop say they found the sound but do not know what is the cause. They can not do anything.
It is difficult to record it properly. But it is possible to hear some noise in the recording. The frequency of the sound is between 200 and 250 Hz. If you knock on the side of a tire, you hear the same tone.

Run flats.... And faulty ones by the sound of it. I don't have this in my s205 but I also have 19" wheels (so less tyre). It sounds like a howl on your video.

Agree, sounds like a RFT issue.
Just to check, you get the noise, regardless of road surface? Most tyres will make a noise on specific road surfaces, but be quiet on others.

No, it is not RFT. It is normal tires. Goodyear. They are marked with MO = Mercedes Original.
No, the noise does not come from the wind. It comes from the wheels.
Yes, various loud noises at various road surface. From disruptive noise to very disruptive noise.
Two other W205 I have driven. Not the same sound. One W246 (B class) I have driven. No noise there either.
I wonder if Mercedes missed sound attenuation mat or something in my car.
