Tires for my 1997 Boxster?

[hoser]

Well, since I started this post, I'll tell you my weather conditions in case since it will make a difference:

I'm in central California:
Summer -- HOT. Usually 100+ of dry heat.
Winter -- some normal rain and fog can be bad (which can make the road more slippery than rain because it's such a light mist). No ice or snow to be concerned about. Pretty temperate all year.
