How can I tell about the longer lasting performance?
Well Michelin claim 10% more mileage over the PS2 in their tests, and given I can get 20K out of a set of PS2 on my fairly extreme GTA for road use, that sounds pretty impressive to me.
PS2s were already the leader for tread life in the ultra high performance category.
The fact that I could get three trackdays out of PS2's with my own car is pretty impressive since my car could melt Eagle F1 GSD03's.
PS2's are still tops for dry driving compared to almost anything out there according to this really detailed Sport Auto test (reputable German publication).
PS2's go down in the ranking in tests by other magazines that are heavily biased for wet driving.
Personally, for that sort of tyre I dont think the level of wet performance is that relevant unless you really want to err on the safe side.
Its great that they are safe for sure, but most folks dont push the car anywhere near the the limit for road use on the wet, certainly I don't..
For wet track days, sure its of some help, but laptimes etc are way more down to the driver at that point, and its just about fun in the wet.
Sport Auto says:
"•The Michelin Pilot Sport 2 is still the tyre to beat in the dry, with only the P Zero matching its performance when the tarmac wasn’t wet."
The Bridgestone Potenza S001 was the overall winner, but was behind the PS2 in the dry

BTW that looks like a very useful site, worth bookmarking.
How can you tell, since they have only been out for a few months now ?
All the tests I've seen put the PS3 below the PS2 in terms of dry performance, but above the PS2 in terms of wet performance.
And both are below Cotinental SC5P, Pirelli PZero and Bridgestone Potenza S001.
