I have close to 30k miles on my P85 and finally need new tires within a month. I've done a lot of research and am surprised that no one has mentioned Pirelli Cinturato P7s. They are 700AA rated and have a 70k mile warranty! The reviews on TireRack are insanely good with people stating that these tires are quiet (even quieter than Hankook Optimos) and have great handling and long life. Has anyone tried these yet? I'm open to other suggestions but can't seem to find anything better. Personally I think the Goodyears and Michelin Primacys stink.
