Bought these to replace P-Zero Rossos that wore very quickly and were very loud (although very grippy). I would rate these Contis as only slightly less grippy and they possess excellent wet weather handling characteristics. Although a little vague on turn in, the tire is very predictable under cornering loads. The area where I am a bit disappointed is in tire noise. One of the reasons I went to these was because of the comments about how quite they are. I find them noisy, except on the smoothest pavement (maybe it's because of the 285 rears that are so wide). That being said, the ride quality is superb.
From cost perspective, these are pretty good value tires (especially due to preliminary wear which is negligible) compared to Michelin, Pirellis and Bridgestones. However, given my previous successes with Sumitomo HTR ZIIIs - they would be my first choice as replacements, because they were quieter with similar performance to the Contis.
