I thought the PS2's were way over rated, had 2 sets, and 2 sets of MSPC, didnt think much of either of them. I am reluctant to buy MPSS as I am not buying the hype. I do like Michelin N1 Slicks though.

 

The PS2s are great tires and IMHO have the right balance of performance (sharpness of turn-in, etc.) and street performance.

I just picked up a set of N2s for the price of one tire after the rear of my N1 had a slow leak. My local Porsche dealer advised me that Porsche does not approve patching tires and because N1s are no longer available, Michelin (and Porsche) picked up the cost of 3 PS2 N2s and I paid for one. Better than a Black Friday special.

Performance wise, just completed a 600 mile run with some Porsche rennlisters and the PS2 N2 tires performed flawlessly.
