I ran Conti DWS on my 128 and generally liked them. They chunked out at the track though Before that on a 325iT, Mich Pilot Exalto A/S and those also were quite decent, even in moderate Mid-Atlantic snow/slush.

On current 135i, ran non-A/S Mich PSS last summer (including many track days) and they were very good for both street and track.

Switched to Blizzaks for winter, and will be swapping for Potenza RE-11 starting next week.

The winter tire / summer tire approach is somewhat a hassle, but all RWD BMWs really suck in the snow without winter tires, and A/S are silly on the track (unless you go once a year). The right rubber makes a huge difference.

But recommend you stick with Mich, Conti, or Bridgestone.
