I bought the DZ 102's because they were priced well and I really needed summer tires. I only have driven on these for a few weeks but must say these tires rock! The dry grip is much better than the factory Michelin's. They have a stiffer sidewall so the my cornering and handling has really improved. And the sound/road noise is a drastic improvement over the factory tires. I have not driven on these tires in the rain yet. I would buy these again from what I have experienced so far. My only complaint so far is that they look less aggressive when mounted on my car then I expected. They are a very nice looking tire off the car and from the side view but, the view of the tread from behind my car is less aggressive than I expected.
