My KDW's saw a lot of ice/snow this winter (more then they should have). I also used mine a lot for auto-xing and a track day. Mine only managed to get 16K before hitting the wear bars (2/32's). They seem to wear much slower when they are down to their last 1-3/32's under autox conditions. The last several autox's I was at showed minimal wear on the tires. The only thing that did them in was a very fast banked sweeper on a gokart track.
If it weren't for the road noise issues as they wear I would go back to them. Actually I take that back, if it weren't for my current financial situation I would have gone back to them. They are a VERY VERY good tire. I think these tires have the ability to keep up with the Falken Azenis (as far as SCCA racing goes STS). If you like performance go with these tires!!!
