Ever since I retired my 1997 SAAB to project car status, my '03 986 2.7L has been my daily driver. It's a fine reliable car that starts every morning and gets me to work. One thing I have noticed about it driving it on a daily basis is that it feeds on a diet of rear tires. I put about 10,000 miles (the rears were at around 40% when I bought the car) on the Michelin Pilot Sports since I bought the car, and they wore down to drag slicks. The good thing is that they wore so evenly, the poly layer under the rubber started to show in the same exact spot on either rear tire. Now that's some seriously precise alignment!
I was looking around at different tires online, perusing the usual "good" brands like Michelin, Pirelli, Continental, etc. I found that (aside from the ContiExtreme DWS -- these look like a superb value) I could put my money in places other than for the Boxster's voracious appetite for soft compound rubber. $300 installed for a Pilot is a bit much for my taste. In my search, I came across a company called Maxxis. Yes, they're not Pirelli. Or Michelin. And call it sacrilege or what have you, but man, these tires are great! Model is the MA-Z4S Victra. They're sticky as hell, have firm sidewalls, and a really aggressive tread pattern. They are rated for 420 tread, AA traction, A temperature (W speed). Best part: I paid $218 including shipping for a rear pair. That's less than the price of a single Pilot Sport. To be fair, I should follow my review in about 10-15k miles (in case they fall apart). Additionally, wet traction is great (I can't speak for snow; haven't been there yet). For those of you with daily driver Porsches out there, give these things a look -- you may be pleasantly surprised.
