Humming sound speed related new F 25

Anyone an idea what the humming sound might coming from?
The noise is speed related.
The dealer told me that it is definitely not from the tires, bearings or brakes.
The car is brand new and hardly driven.

Thanks for your help.

I haven't heard a humming sound. Is it wind?

No it has nothing to do with wind noise.

RFT can do some weird things, my brand new MCS(Mini Cooper S) came with RFT and I had a humming sound coming from the car, and they never wanted to admit it was the RFT, since they were new. So I did the move myself, got normal tires(toyo proxex 4), and it was all gone.......

Tires are always a good suspect for that sort of noise.

Agreed!
Those RFTs are pretty bad. Although I do think that they're not as loud in my F25 as they were in my MCS and 328i. Maybe because I'm further away from the wheel well? Dunno.

I haven't noticed a lot of wind noise in this car. But I'm coming from smaller, louder cars. Maybe the F25 is downright loud compared to most other crossovers?

They found the problem, after they changed the wheels with the 20" the noise was gone.
They ordered new 17" P7's hopefully they do not come with the same issue.

Traded in the 17" with humming P7's for 20 wheels with P zero's. Great looks and no noise.

With trade in of the 17", I paid the dealer 2500 Euro. The price of the 20" with tires is in Europe 3800 Euro.

Any impact on ride quality / comfort?
