What is the difference between Michelin pilot sport, and that Michelin pilot SupersPort?

I need to change my tires, and the name on the tires that I have right now says Mission pilot sport, but they have the tread of the new Michelin SupersPort. Is it only change of name, or is it a completely new tire ?

If I look at the tires that iPhone presumptively they have the same tread pattern as the new super sport. Apparently I cannot Dix the super sport and the private sports..

Any comments on that subject ?

Thank you i, in advance
George
