I think for the first time ever, I am going to have 3 sets of street wheels for a car. I have 20” Summers and 19” Snows now, but bought a set of Titan7 TS5 wheels to replace my heavy stock 20” summer wheels. I am leaning towards swapping the Summer tires onto the new wheels and buying Michelin Pilot Sport All Season 4 for the stock 20” wheels. Reviews of that tire are fantastic and it should be great in later winter/early spring and late fall/early winter. Snows give up a lot of performance but they are best for serious snow and we get some of that here in NH where I live. We have a Cayenne that I put snow wheels on in late fall so I will be OK if there is an unexpected heavy snow and I have to go somewhere before I have time to swap wheels on the M5 and I don’t feel like the Pilot Sport All Seasons would be good enough.

There is a dearth of 20” snows in 275/285 or even 265/275 so it seems best to stick with the 19s for snows. Even with 19s, sizes are limited. I have 265 square on 19x9.5 now but may go to 275 square when I replace them.
