I'll take a BMW with RWD and Snow tires over one with X-Drive and All seasons any day of the week.
Why do so many forget that a/s tires harden in the cold. Your dry pavement grip is compromised even without snow and ice on the ground.
Not to mention the OP got "ultra high performance" all seasons; which means they are pretty close to summer tires.
If you're spending the money already on extra rims and tires, it doesn't make any sense. The extra foot or two of braking distance may mean the difference between crashing or driving away.
