I've had these for about 2000 miles now, with a very evenly combined city / highway mixture, having just completed a 1000 mile road trip. I was initially very attracted to the price of the DZ102, but was slightly concerned about how they would perform in wet conditions, especially after reading several reviews regarding the performance of the DZ101. These tires absolutely love warm conditions, and stick very well to dry pavement, with fantastic feedback at highway speeds, and in city driving as well. Under wet conditions, the tires didn't flinch. They have great feedback, and allow only the slightest amount of give when they're pushed hard, but have a very linear feel to them that gives you plenty of notice when they're on the edge. They're very quiet on the highway, with minimal road noise; it's not imperceptible, but still remarkably quiet. These made the car feel very planted, and I didn't notice any 'tracking' or 'squirming', although I made sure to get an alignment immediately afterwards.
So far, great tire for the price. I'll update my review after I've covered some more miles.
