I tried searching and didn't come up with a whole lot of info. A good friend of mine has a 2008 F-250 King Ranch with the factory 20" wheels and 3 out of 4 are cracked. He's tried talking to ford and they will not do anything to help with the issue. Has anyone else had these king ranch 20's crack or is this an isolated issue? He bought the truck used and one would never know how it was driven before or possibly abused. Any input is appreciated.
