Has anyone experience with the Conti Road Attack 3? I have driven 13.000 km with Michelin PR4 and am not satisfied . I was pleased with them for about 8,000 km and since they have just gotten worse and worse. The bike has become heavy steering and the tire seizes all asphalt strips. I would like a tire that is more agile than PR4 and which retains its features. On my previous bike I had Metzler M7RR, which I thought was really good, but they did not last for so long.
