Even Continental was disappointed to hear about the wear and are having me take the car to a Continental dealer to inspect the wear and potentially help me out. There is no tread life warranty on the DW tires.
Anyway, there you have it.
Hunh. A bona fide mystery - which some have reproduced. Good job getting in there to so promptly rule out alignment! Wow.
Always find it entertaining when the manufacturer / dealer says, "Hunh. That's weird...!"
