I have a 2011 320d,bought 3 wks ago with 17000m. On test drive, handling & stability felt good. Before collection the rear tyres were replaced with Bridgestones (Continental Contacts on front). Now the car tramlines & at times feels very unstable, particularly on bumpy corners - can you diagnose?
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
What you describe points to the tyre replacement at the cause, however, alignment and wheel balance should also be checked, as well as suspenion wear.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
