Well, they're toast after about 5k road miles and a LOT of sliding around (and into) cones. The tread is nearly shot on front, and about 2/32" on the rear, so I'll rotate them and finish the auto-x season, but they are slow now. After this many heat cycles they have gone off completely, and are very hard. The last 2-3 events they've dropped significantly in grip, but they seem to be done now. They're still pretty quiet and have a good ride, and seem to do well in the rain with 3/32" left. Overall, I'll reccommend them over the AVS ES100s and the Kuhmo 712s for street use, but the Hankooks seem to be the new bargain tire for semi-serious autocrossing.
