I have the 336's and they are awesome. When I move to my winter 219's (255/19's) there is a bit of an adjustment. Not nearly as bad as when I bought 18's for my winters (quickly sold for 19"s) but i can feel the car with a bit more float but still feels very stable. I get the same from my M3 when I go from my 19's to the 18's, under hard acceleration i can feel the ass floating.

My wife always gets complements on the 315's on the rears all the time. I get a kick out of guys commenting on her tires. Makes the car look like a tank from behind. She always hates it when it starts getting cold because she knows I will be removing the massive 275's/315's for the puny 255's. She just asked me today when am I going to but her awesome wheels back on the car.
