Also, stock M5s that come with Michelins do not come with the ps4 but the ps4s. The pilot sport 4 is a different tire than the 4S->

I actually meant the PS4S - I had them on my M550ix before the M5CP - but you are correct - I quoted the treadwear for the PS4 which I didn't even know existed lol. Still at 300 tread wear though. I must also admit - I did not know the Pzeros are 220? Actually makes me like my - what I thought was unlucky - "gift" of PZero's on my car. That said - tread wear ratings are tricky these days. The original Cup 1's were - I believe 60 tread wear - and the PS2's are 180 - but they are just as soft. My understanding is that the ratings combine different compound ratings within the same tire and perhaps average them out...I don't know.
