I'm have had both Conti & Mich tires, on three separate w204, and hated them for slightly different reasons. For 703$ all in, balanced and aligned - I had a big tire chain pricematch Walmart, and put the DSW 06 on. I gave them 500mi, but they still had some vibration at 75/80 that the tire shop couldn't seem to balance out, even after returning to have it done again. I was still getting a thrumming that felt like flat spots. I figured I'd take it to MB to have them balance, before looking at returning them or rims as culprits. MB wasn't happy balancing someone else's sale, but I told them to if they wanted, they could force balance them. Which of course, they jumped at. So, after paying almost $195 more - and I have to say, for robbery -- it was worth every penny, not even a ripple, a wiggle or pull at any speed. The feel is total glass, just total control, and a quiet hum. Rides way better at 40K, than either of the two brand new 2013/2014 w204's that I had. Handles better too. Changed my view of the car for the better, and deepened my appreciation for the platform and chassis. They aren't perfect, I also lost about 2mpg HWY, and about even in the city, but they gave me a drastic improvement ride wise, and knowing I can hit a pothole and not have to replace a tire every 6 months or so. Never again OEM!
