The difference of comfort between runflat and non runflat tire was not noticeable. I suggest this is due to the Air suspension of the car.
The problem was that the front Michelin Pilot Sport 5 were 2 cm lower than the rear and the size didn't match that of the original tires. The xdrive error appear and had to sold them. Now I am considering between Michelin Primacy 3 runflat (which the car originally was fitted) with BMW star and Pirelli P zero PZ4 non runflat with BMW star.
The attachment is photo of Michelin PS5 and the tire difference between front and rear.
