Bought these as a summer only tire and looking for a quicker steering reaction than the previous Conti Extreme Contact DW. These definitely fit the criteria. The downside, as anticipated, is a less compliant ride. Tires transmit more harshness from less than perfect road surfaces, maybe due to the sidewall stiffness that provides the response. No issues yet in the dry, pretty good in the wet with predictable behavior so far. Wear seems to be acceptable although, as with other staggered fitments on my BMWs, the rear tires wear the center of the tread quicker than the edges, and it is NOT due to overinflation.
It will be interesting to watch the tread wear next summer. With about 5k miles on then, the tread is around 8.5-9/32 on front and rear tires.
