I got a flat tire earlier this week (rear passenger side), and had it towed to the dealer, and they called me yesterday to tell me that my tire had been discontinued (I have 2006 CS OEM tires, I believe they are continental as well).

They located a tire for me on the east coast, and are having it shipped out here to CA. The car will be ready on Monday.

I want my car back!

The bright side is, I don't have to have my other rear tire replaced (the wear on the "old" tire is little enough that they will not have to replace both).
