An interesting thread on another forum, most relevant to Michelin Super Sports from bottom of page 1:
QUOTE:
"Without going into "deep" politics as to why to date we haven't got homologation for the 991 on Pilot Super Sport, I envisage this should come to pass in 2015, and following that, the back homologation of the PSS onto the older generation cars is planned.
Now as a fellow Porsche lover, I'd love it to happen, as it would be a clincher for me to buy that Porsche... I get free tyres! just need the right car to put them on..
We'd like this homologation, as it would allow us to replace some of the PS2 fitments with the new super sports."
