I've never tried Pirelli on the 911, but on the Boxsters both 986 and 987 the Italian brand was deficient in two ways. The wear rate was very bad (8.000km the rears) and the driving characteristics of the tyres deteriorated very soon after.

The Michelin are the best in many areas except the channeling of standing water an area which I find the Bridgestone Potenza N1 very efficient. Our highways hold a lot of standing water because when it rains (not as often as elsewhere) it is frequently in the form of almost a tempest. Other wide tyres on sportscars are quite useless and dangerous.

I also rate the Bridgestones highly in terms of handling, roadholding, noise, wear. However, the sidewalls are stiffer than the Michelin's and this gives a bouncy feel on continuous bumps.
