Continental sportcontact 5 on my 220d.
I think they're run flat - which can make the car abit crashey over bumps/ pot holes due to the extra side wall stiffness.. I'm hoping a replacement set of Pirelli or Michelin which are nonrun flat will improve this a little. Has anyone swooped out their contis for non run flat and did it make a difference?
Ps over all I love this car and would still recommend despite a number of minor issues from new -interior panel rattles, collision avoidance sensor replaced twice, and a ratcheting noise when pulling out of junctions occasionally.. All now fixed with the exception of the last one which is in progress
