[The H is Silent]

I recall having the PS2 on my e90. At some point the PS3 was released but was not the direct successor, but rather the PSS became that new tire to go after. If this new tire supplants the PSS then it's interesting that they abandoned the super sport naming so quickly to go back the pilot sport.

On a somewhat related note, the 4S just seems like a poor naming choice as it immediately conjures up the idea of a 4 season tire to me. Then again, what do I know, I'm just buying tires...
