I'm not making this distinction to say you're wrong. I'm simply saying the source of info is more reliable. If you can find more credible sourcing (which would have to be directly from some source at Michelin) then please share it because I also do not want to be putting confusing or conflicting info here.
Cheers.


Edit: I see the comment section of that article references a chat with Michelin also confirming it is a replacement. However, there is a twist as it replaces all generic SS but OE manufactured SS will be available until 2017. Can someone explain the differences between 'OE Manufacturer' and 'generic' tires in this situation? I took OE meaning something like Porsche's N rating. Since SS's aren't N rated, they will soon not be available to us. That's what I'm understanding but please correct me if that's wrong.

Expect a PSS2 or equivalent 1-3 years from now.

Ideally with AD08R and the RE71R out, Michelin needs to move the PS4 more upmarket towards the PSS into the max performance category and the PSS2 needs to move into the extreme performance category.

Edit:
Here's the video. He says 'replacement'

I found a link: http://www.tyrereviews.co.uk/Article...ss-Release.htm

At the bottom of the page, SS is on top.


EDIT: Read some additional info. Sticking to what I first said. Super sports replacement is due in ~2017 apparently. PS4 seems like it is very similar in performance to SS, but will not be the top tire.

the MPS4 was that tire ...

I doubt that Evo would get this (that) wrong... I guess we will wait and see.

Its all a bit academic/moot at the moment since we cant seem to get the MPSS in either 19" or 20" 305 anyhoo ...

The larger MPSS (19, 20) will still be made for OE manufacturer which DOES NOT INCLUDE PORSCHE (because no N rating) until they are phased out by the MPS4 in the not too distant future (mid 2017 for most sizes and late 2017 for all sizes). To add more to the pile, they have a successor to the MPS4 in the works slated for a late 2017 release, but that's all the details he would give me on that product.

He would not tell me when production of the 305/19s would officially stop but a 'wink wink' 'elbow nudge' basically slotted that at Q3 of this year. After that the hiatus between MPSS and MPS4 is about a year for us and MPSS will remain scarce until then.
