Two flats at different times on the same day convinced me that it might be prudent to have a complete backup set and since I was putting new wheels on, I decided to get the Michelin Pilot Sports (not PS2's) with the new wheels. The Eagles on the original wheels are in storage, new Ronal wheels with Pilot Sports are currently on the car. WMichaels is running the BFG KDW's on his car which he uses for autocross. And Hey, if you are reading on the other site, be sure to post a "hi" or something!
