None of the above
I have put loads of standard P-Zero's on mine over the last few years (Not Nero or Rosso). These are the ones fitted on the Pirelli Edition from the factory.
I had a pair of Rosso's on the front of mine when I bought it. When the tread gets down to 3-4mm the grip is appalling in the wet. The case is similar with the Nero's my dad had on a Jaguar X-Type a few years back. The standard P-Zero's still work well when nearly bald! (In my experience).
This is just my thoughts but...
I got 4 Goodyear Eagle F1 Asymmetric 2's put on 2 weeks ago for a change.
Make sure they look after your wheels. Even though I asked them to be careful they still damaged all 4 but 1 needs professional correction!
