The Audi A3 came with Pirelli P-Zero tires. Let me just say, they sucked. They were always pretty bad but the last couple of months they had become very loud. Recently the threads(!) started showing in the middle ridge. So, looked for a deal and got a reasonable but not great one at Costco.
I've now had some Michelin Pilot Sport A/S's on for a couple of weeks and I love them! Very quiet and sticky. I just hope they last. They are considered "Ultra high performance all season". According to Tirerack the ratings for all conditions, including wet, are pretty good. I've had the chance to take a couple of quick curves in the dry and they feel so much tighter than the Pirelli's. Not a hint of squeal yet either. I don't know if or when I'll have a chance to autocross them but if I do I'll try to report back on the results.
