I replaced my P-Zeros at 7800 miles (non-Brembo) and stuffed them back in the attic so I don't have to look at them....just plain hideous tires for a DD. My new set are Firestone Firehawks, and even though they have a softer sidewall, their ride quality is an enormous improvement over the P-Nero's. The Firehawks are so smooth I barely feel the highway pavement, and the tire noise, almost no-existent. I'm sure the P-Nero's have their place, but since I'm not a track hound, they are of no use to me.
