250 miles or so on the tires:
--yep, ride is still much smoother. Expansion joints on the highway are now palatable to my wife
--ride noise is noticably less on the highway
--cornering is better, but can feel that the sidewalls are softer. Several spots around town require a hard turn over washboard pavement...DSC does not engage now (it did with the runflats). So, noticably more control
--Took the car through the tramlining spot (semi truck ruts in the highway)...no problem to roll right through them and out at the end...easier to control.
--Fuel economy: no change noted. 24MPG in a mix of city/highway.
