Tire Rack does not list a winter tire package for the 2008 S63. They do sell one for the 2006 S55. Does anyone know if it will fit? Brake caliper size is a major factor.

 

Well first off do you want wheels or tires, or both? I imagine you have 19s which is causing the trouble finding a tire, but just look at the tire sizes of your summer and search for them in a snow tire avoiding the automatic thing on their site altogether. Also their staff is normally pretty good if you just call them and explain it you should be fine. Sometimes you get narrower rears for the winter though so the sizes might not be exact. I'm sure your dealer can tell you what kind of tires to get, its prob cheaper to get sizes from them and then order on tirerack though. I just ordered blizzack lm25s for the e55, those are good and so are dunlop M3 winter sports.
