This is definatley a long running debate, and don't want to come across that I have no idea how I want my tires rotated. I'm mostly curious about what people are actually doing with their trucks and anyone that has supporting evidence like Dr. Evil of what is actually working on the 2011 SDs.
I'd also like Cory to explore why the Ford Shop manuals don't match the recommendation in owner's manual. As of today (3 June 2011) both the Ford (owner's manual) and the the National Tire and Rim Association recommend that a REARWARD CROSS pattern for rear wheel drive and 4X4 vehicles. Honestly, this is what I prefer. But if you ask your local Ford dealer to reference their shop manual, it recommends front to back. Ford should take a position in this debate, and it should be the same in both publications.
Altogether different....my Ford dealer, apparently not knowing the difference between cross patterns, actually performed a FORWARD CROSS (for forward drive vehicles only). Debates aside, this is probably the worst possible option available. I always place numbers inside the 'C' on my Continental AT tires so I can keep tabs on where the tires move.
