I just talked with Tire Tack and they said I can do 275/40/21 (the stock front size) on all 4 corners. He said the tire will fit a wheel from 9-11" wide.

Im reaching out to fellow Bimmerposters to confirm if this will work (winter setup) and not cause any problems. He said the rolling diameter is exactly the same.

He found a really good snow rated all season tire for me at a great price.

I look forward to your feedback.
