Definitely worth checking for transportation blocks, but I imagine there won't be any there.

I do suspect the run-flats are amplifying the road imperfections as road quality deteriorates. Had the same issue on my E91 330d, non run-flats changed the way the rear damped the poor surfaces.

Are you thinking of getting 18" wheels to allow keeping the 17" as is? If not, 17" non run-flats will probably give the best ride quality. I suppose it depends how much you are willing to experiment.

As I am going to change over to non rfs I thought I might as well go to a slightly bigger wheel for cosmetic reasons - I just hope that doesn't defeat the purpose of the exercise!
