Comfort/ride quality wise - slightly better with 19". Not that big difference that you would think.
A bigger difference is in grip levels. 19" ( higher sidewalls ) gripping better it seems. Especially when exiting a corner ( side force on the tyre ).
Excellent. Thanks for the quick response. It makes sense that you'd achieve better grip with the 19"s. Glad to hear that you don't give up much comfort/ride quality with the 20"s. Since most of us may take our M5s to the track once a year or less, I'm thinking that 20"s are going to be a very popular choice.
