FWIW, I've been running Sumitomo HTR Z IIIs on my Boxster for daily driving in California, and they are just fine. In dry and wet they handle well and don't have the same road noise of the P-Zero Rosso that came stock on my car. I cannot speak for how they might handle in colder weather/conditions, but they aren't A/S tires so I wouldn't recommend using them in places where there is 'real' winter.

I just swapped out the rear tires, but I'm still on my first set of fronts. I'll have to dig back through the records on what my mileage was, but I got about 2-years of steady use out of the rears and the fronts are still going.
