I am looking to replace the Pirelli P Zeros on my 996 c2 , but Im not sure what to go for ie straight replacement Pirellis or I have been advised to go for Bridgestone Potenza S001 XL, I am looking for 225/40/18 and 285/30/18 there is hardly any difference in price, and the car does not get a hard life on track days or such like just normal high speed motorway and occasional back roads , any advice would be appreciated
