I have about 30K mi. on my SP Sport 5000's and they're the best tires I ever bought. I had been running 215/50 KDW's. The Dunlops are better in every respect except they roll over slightly more under hard cornering (could be due to the size difference rather than construction - the Dunlops are 205/55). I expected slightly worse traction due to the all-season tread, but they actually turned out to be better than the KDW's in all conditions. Add to that the better treadwear and decreased noise, and it's turned out to be a great tire. I also used them all winter, which was pretty snowy here last year, and no problems.
