With mixed weather driving, 20” is the only choice. I drove 1100 miles in one day from sun through rain, sleet, ice, then snow. The issue is also temperature changes. Even if it’s dry out and cold, summer tires skate around the dry pavement. I travel across country and I am not going to worry about a flat tire with road conditions like pot holes and construction zones with a ultra thin sidewall. Not on a luxury SUV. If I leave PA in the winter and go to Miami, snow tires and wheels will look ridiculous and ride horrible south of South Carolina. This is that "mix weather driving" I am talking about. Ride with the 20”ers are perfect with my 50i M-Sport an I love the look. There is no AS options for 22"ers and only one AS tire for the 21"ers.
