I vote for Bridge Expedia S01's, one of the two OEMs.
Very progressive at the limit, excellent grip, decent life, good looks. Said to be better on the wet than P-Zeros, but since the car is almost undrivable anyway, not sure that makes a difference.
Read strong advice against using anything but OEM tires because cars such as the 355 are very sensitive to tire behaviour (rigidity, etc ...), handling degrades if you fit something else.
