What is the warranty policy for Continental tires?

I'm hoping someone can shed some light on the warranty policy for Continental tires. I recently purchased a set of ContiProContact RX tires and was wondering if anyone knows what's covered under their warranty program? Specifically, I'd like to know about the mileage guarantee, tread wear protection, and any potential coverage for defects or uneven wear. Has anyone else had experience with Continental's warranty policy?
