I changed my mind. I'll probably go for 195/70R14 Blizzacks (asumming that they make them). That will raise my profile for snow/ice/pothole driving and maintain my revs/mi (842 versus 845) so that I don't need to reprogram that parameter in my PCM. Obviously, these tires won't fit on the SVT rims.

On the other hand, for this price, I could take them to a reconditioner and have a sweet set of summer rims...
