I'm having major belt service on my 575M. Tires have good tread but too much age. Heart says Pirelli P-Zero Rossos since first owner of my old 365GTC speciale was Pirelli CEO Leopoldo Pirelli and Pirelli compted me a set of tires for the car many years ago. But I have heard very good things about the new Michelins. Bear in mind that I will not track the car except for regular 'parade' laps at the Glen and Lime Rock. On public roads, including surrounding Adirondack 2-lanes I drive assertively but not aggressively - tho' SWMBO might dissent from this view. What say this panel of experts?
