Bro

I have a 2013 C-Max Sel. It has 12,000 miles on it. Since my last trip to my dealer I have been recieving emails and mail telling me "tires require immediate replacement". The tires look fine, tread looks fine, I cannot understand. What kind of tire needs replacement after 12,000 miles. Is this normal for the C-Max? What's everyone elses experience been with the Michelin tires? I use this vehicle for picking up my grandkids from school and it has no hard driving on it.
