We just bought our P8 today. After being adamant I'd prefer 19" rims, I test drove both 19" and 20" versions and went with 20" instead, herein eating my words. My reasons:
1) The 19's had a noticeably softer ride, but also a little more vague and "SUV" feeling. I actually preferred the ride on the 20's - but my daily driver is a bone-jarring model 3.
2) Michelin's soon-to-be-introduced Pilot Sport SUV-EV tire will be available for the 20" wheels but not 19".
3) Harmon-Kardon's "adequate audio" seems to only be paired with 20" rims in my area.
4) They do look cooler and I'm willing to be more careful over rough pavement edges, etc common in my area.
