Frau Putzer managed to shred some "green" Michelin MXM4's in 48k miles. There were big chunk of rubber tearing off the tread blocks. After 25k miles of Frau Putzer's abuse, the DWS06's were still in one piece. However, my gripe with the DWS06's and two sets of DW's I've had is that they need a lot of pressure to wear evenly. After 25k miles, at 43 PSI to 44 PSI, Frau Putzer's DWS06's had ~5/32" of tread on the side channels, and ~6.5/32" to ~7/32" of tread in the middle. The DW's on my Cobalt SS need 42 PSI to wear evenly.
I've found that non-run-flat Bridgestone's and Michelin's wear fairly evenly at about four PSI over what BMW calls for on the door jamb decals (for speeds < 100 MPH). So, I only put Bridgestone's or Michelin's on our BMW's now. But, I'm done with Michelin "green" tires.
I have gone between runflat Pirelli P7 and Bridgestone Pole Position RE960 tires on two different X3 models and been pretty happy with both. The Bridgestones seem better to me somehow, both in the ride comfort as well as durability. You'll not get the smoothness of a non-runflat, of course, but lugging around a spare isn't an option for me.
