My 2011 has 14k miles... After the 2nd tire rotation, I noticed a wobble. Took the truck to the dealer. They checked everything out and the truck was ok. They rotated the tires again (3rd rotation) and the wobble was gone. They told me the tires were cupping and that the tires had belt shift. Although the tires are out of warranty (12 months/12,000 miles), they advised me to contact Ford at an 800 number to see if they could help me (good will). I will call them tomorrow. Has anyone else experienced this?
