F83 squeaking roof

[smiko]

Hi there
Can you advice how to eliminate roof cracking noises?
Can we elimnate it at all or its a vert so it should work like this?

I have 2016 f83 stock setup on 19 inch summer and 18 inch winter tires.
This is my daily. I have it for last 5 years, the problem is getting worse with every year, I am really tired of the roof squeking every 10secconds on a every tiny bump or mark on the road

90k km so far.
The car is well kept and I really take care of it.

I regularly use bmw gummipflege, thick layer on every rubber of the roof
Additionaly thick lithiumn grease on the 2 metal locks of the roof. Still noisy.

Cracking on 18’ wheels is by far lower than on 19’ say 70% reduced, but still you can hear it every minute.

I ever reduced tire pressure to 2.0bar its better but still not happy with the result.

Any other tips??

Maybe bmw TIS have some manuals for fitting of the roof? Maybe it has loosened somwhere after these years?

Any ideas?

I have a 2015 F83. My solution was a louder radio.
