I'm really happy with Michelin Pilot Sport PS2 tires. I have them on my 987 and my c230 sedan. While I only have 3500 miles on the 987, the c230 has 20k miles on it and the tires still have over 60% tread left on them. They are expensive, but they have great grip, are pretty quiet and seem to last. I drive the canyons everyday to work and while I don't push the mercedes to the limits, I don't drive like a granny either. So I am quiet pleased with the tread wear. Only time will tell with the 987. These are summer tires so the wet weather traction is only moderate at best. Definatly not for snow, but I don't expect many people will driving thier Boxsters in the snow and if you do you should have a set of winter tires. Anyhow, thats my opinion. I look forward to seeing what other people have to say.
