I rotate mine every 5500 miles. On my Y2K dually, I rotated all 7 in the sequence listed in the owners manual and over the 11 years I got over 70K miles on a set. They were all steel though. On the 2011 with alcoas, I rotate front side to side and rear as well, shiny side out. The original Generals were pure junk and started tread separation at 7,000 miles, so I had them replaced with Michelins. Same rotation sequence and with 35,000, no issues. Now, when I had the Michelins put on, I went to six tire sealers and told them that I am very particular and wanted NO DAMAGE to my wheels. One shop agreed and the owner said that he would do the work himself. As luck would have it, their NO TOUCH tire machine gouged a front wheel. They bought a new one from Ram, ($675.) and replaced it with no grief. If one was to dismount and remount tires on these wheels for each rotation cycle, there will be damage sooner or later, that's a fact. I believe that a lot of the tire wear and alignment issues are with the 4X4 trucks, at least that's the truck in most of the posts on these issues. Anyway, that's my take on this....
