Looks like I've sort of answered my own question here, online help on Michelin's website:
MICHELIN – Paul: Hello, I am Paul, your Michelin advisor. How may I help you?
You: Hello,
MICHELIN – Paul: Good afternoon.
You: I heard somewhere (I cant remember where) that you would be phasing out Pilot Super Sports in favour of Pilot Sport 4's, is that correct?
MICHELIN – Paul: Thank you for your question.
MICHELIN – Paul: Yes. Pilot Sport 4 is a development of Pilot Super Sport. However, at the moment Pilot Super Sport is still being produced
MICHELIN – Paul: Pilot Sport 4 is a new tyre from the beginning of this year and there will be more size releases during this year.
You: So does that mean Pilot Sport 4's are an improvement over Super Sports?
MICHELIN – Paul: Yes. It has technologies in common
MICHELIN – Paul: Longevity and fuel consumption has been improved.
MICHELIN – Paul: Would you like me to send you further information about Pilot Sport 4 per email?
MICHELIN – Paul: May I please ask what vehicle so you drive?
You: Ok, thanks for your help. No thanks, I'm familiar with the Super Sports so if the PS4's are an improvement I think I'll buy some.
MICHELIN – Paul: You are welcome. Can I recommend you a tyre dealer near to your place?
You: I think I'll be ok thanks, there's a place I normally use so I'll go there.
MICHELIN – Paul: Excellent. May I help you with something else?
You: No thanks that was all. Thanks for your help.
MICHELIN – Paul: My pleasure.
Have a nice weekend.
