Adequate for 3 seasons. Wore fairly quickly.
I've driven these for coming up on 3 years in 4 season weather. In wet and dry they're pretty decent. Notably better in wet than Pirelli P7 Plus I had on my former car. (Those didn't hydroplane easily, but had poor wet traction). That said these are pretty poor in winter. Driving conservatively, I've slid around a bit on these. Almost bought a separate set last year but fortunately the last 2 winters have been mild. Biggest thing currently is at ~31k miles the shoulders are pretty well worn. The sipes are almost gone so it's time to replace these which is pretty short life even for a UHP all season tire that hasn't been driven hard. They were rotated regularly and tire pressure was maintained.
