Yeah, most people notice (I do also) that on anything less than new asphalt, it does generate a lot of road noise. A good bit of that is coming from the runflats, unfortunately that's just an unavoidable aspect of them.

Users here have reported a fairly significant reduction in noise upon switching to traditional tires.

What kind of "unbearable noises" are you hearing? My F32 is lowered on adaptive suspension and while I sometimes wish it was quieter in the cabin I wouldn't say it makes funny or unbearable noises.

Runflat tires are probably noisier than regular tires, they can make the ride more harsh as well.

It's the combination of huge wheels (I'm guessing 19"), runflats with skinny sidewalls, and sports suspension.

The first option would be to replace the tyres with non-runflats. If that's not enough you'd have to go to 18" wheels & tyres; and finally go to SE/Luxury/Adaptive suspension.

Alternatively you do as I did in my 320D M-Sport Touring (19" runflats and sports suspension) and turn the stereo up - or as I did on my Z4M and fit a very loud exhaust.
