Sounds to me like you are using runflat tyres and they are worn out and due to be replaced. I had the same experience after havinf done 20K miles on my car and thought it was the suspension. BMW said it was the tracking and duly charged me to adjust this but it turned out to be worn runflats. They say that after 15k they should be replaced.
no mr_grinche, i do not have RFT ... unfortunately

Had similar problems a few months ago..
Balance and Rotate/Remount your tires
Do your alignment - people forget this and it is critical with every tyre rotation IMHO. You should see the Toe/Camber readings to see how off you can get in just 5K miles...
Oh..yes..and I do rotate and have had no issues with doing this even though I know BMW doesn't reccommend it...

thank you subarashi, i have had the alignment done in July when i had that problem with the summer tires and i have put the winter ones. I had the feeling that the car was pushing in left side and i had the angles done. maybe the mechanic didn't do it well and now i have these problems?

I only get this feeling when going at high speeds past 80mph passing other cars. So you only get the feeling when your passing other cars?

80 mp/h that would be around 130 km/h ... i could definitely say that when i pass 120km/h i can feel that. and at 200km/h the feeling passing a truck is quite horrible. i really have to keep the steering wheel really tight.
i hope the tires are the problem and when i will change them the problem will be solved. i hope...
but i still do not understand why this situation was not present there at the beginning...

unfortunately tires do not always wear evenly, and it's necessary to balance in between changes. this could be due to alignment, road contours, driving habits, so many factors. but definitely sounds like a problem with tire/wheel balance.

I have the car for about 8 months now. At the beginning the feeling in the car was great... but for the last 2 or 3 months the car doesn't have the same stability as before. it feels wobbly when i pass a bigger car like a TIR or a VAN and it feels like i do not have control over the steering wheel(i am exaggerating the feeling so you could understand better what it feels).
It is like the car is going from a side to another if i do not correct the direction with the steering wheel.
The mechanic said that nothing is wrong with the mechanical part under the car and also the steering wheel has it's movement in it's good limits. He said that i should change the tires. because i got into winter tires sooner... that is because of an unfortunately event(i found one morning 2 of my tires chopped with a knife or something).

So, if any of you would have any idea about what would be the problem i would appreciate an answer.

Thank you very much.
I have been getting similar symptoms to yourself over the last couple of weeks, ive just had the wheel balance checked to find they were miles out, like 200 grammes on the back and 80 g on the front. The balance was only done in july when i changed to non rft's. Now drives perfect again.

From what I can tell you now are using snow tires that might be the issue?
