I know I can get a set of the Michelin Pilot Sport AS3s for $877 out the door right now at Costco.
Would be cheaper than PSS and a winter set, although I have a winter set in my attic in 16 inch from my old GTI (225/50 16 Wintersport M3).
Guess I'd have to find a 16 inch wheel that fit the ZHP and swap over if I were to go the summer tire route.
My DD has had the Conti DW tires and have been really happy with how quiet and refined the ride is. Sticky ultimate grip and wearing quite well.
What I hate about buying tires is that there is seemingly no 'definitive' answer, but the PSS is as close as it has come.
Comes down to pay to play I guess.
