Mike689,

Reference tires for your Boxster:

1) I have been very happy with Sumitomo HTR Z II & IIIs.

2) They are about $300 for HTR ZIIs and $340 for HTR ZIIIs (that is a set of 4, 17 inch tires)

3) ZIIs are Ultra High Performance Summer and ZIIIs are Max Performance Summer.

4) This first tier and second tier stuff is BS. Tires are regulated they have to meet certain standards. All you have to do is check their ratings (Temperature, Traction, Wear). The better tires will be rated higher in each category, and of course you will pay more for higher ratings.

5) HTR ZIIs are rated 360 A A
HTR ZIIIs are rated 300 AA A

6) I've had both and I currently have HTR ZIIs on my 99 Boxster w/255,000 miles.

Just my 2 cents.
