Winter Tires for 07' RS4

[mtmscs4]

Just purchased my 07' Sprint Blue RS4 a couples weeks ago. This car is incredible. Wondering if any current RS4 owners have some advice on winter tires? Since Tirerack doesn't offer a 19" Pirelli Snowsport I'm investigating downsizing to an 18" to stay with Pirelli. Blizzaks are not my favorite.

Also, does anyone have a source to purchase OEM RS4 19" rims? Thanks.

I use 255/35/19 Dunlop Wintersport 3D that are great, got them from tire rack.

I'm running Dunlop WinterSport M3 if I recall correctly. The WinterSport 3D is a better option, but only if you go 255 wide. The M3 is very very good, but the 3D is excellent.
