Posting here because the OP helped me decide on my fitment. Same HRE fitment except with FF11s. Michelin PS4S Rubber is 255/35/20 Front, 295/30/20 Rear. 2020 M550i w/ dynamic suspension. I would say the front is flush and the rear has a little poke. Went with 295 for 0% rotating difference. Rear tire looks a little stretched on 10.5 rear. I actually made the mistake of going with the PS4S, when originally I was looking for the same fitment as OP then realized he had all seasons. Once I saw the rear stretch, I was pissed...until it was mounted. After seeing the 295 rear PS4S mounted, decided to go with Dinan springs to complete the look... And I will update after. Picture is before Dinan.

Just getting started...
