Gnil:

As a side note, isn't their anything a fit fishy about the PSS not being N rated ?  As Ferdie, mentions, the PSS was developed on the 997.2  and all the mules at the time were fitted with those . 

I can't believe the best road tire from Michelin can't be N rated .......  yes

I have long wondered about the lack of a recommendation and OEM production release for Michelin PSS tyres for recent 911 models. 
In view of Michelin being the tyre sponsor for motor sport activities and the long relationship between the two marques it seems weird that they would not have been able to eliminate any technical problems which might initially have delayed the release. I suspect that it is now more of a political problem resulting from commercial differences or a personality clash somewhere. 
If so, it's a shame the customers have to suffer for it.
