Why does the F31 wander and bounce around in ruts and asphalt patches?

The most common cause is worn rubber bushings in the suspension, even if the wheel alignment is fine. Worn control arms and wheel bearings also add play. Cracked bushings are replaced, usually in pairs.

Can runflat tyres cause F30/F31 wandering?

Yes, runflat tyres can increase wandering and deviation in ruts. Switching to regular tyres has removed the wandering even though the angles were not touched. The characteristics of winter tyres can also make the rear end search.

F31 xDrive pulls in one direction even though alignment has been done. What can cause it?

The cause can be the rear wheels' camber, i.e. the wheel's tilt angle, and adjusting it calmed the pull somewhat. Tyre size and road camber also make the car sensitive to pulling, and some cars always pull slightly.
