The Pirelli PZeros are shot and its time for some new skins on the 360. I have been hearing about the new PZero Corsa, but can't seem to find it in the right size (275 40 18). I have also heard the Yokos are real hard and that Ferrari is putting Bridgestones on the Enzo. Who has some actual experiences they can share about tires. I want great grip and a suitable ride, but going to Hoosiers doesn't make sense to me for everyday driving. Any help?
