Rotating tires on a dually

My Chevy manual recommends rotating them at 7,500 miles on my 3500 DRW truck. But when I stopped at the tire shop I have used for years, I was told I have 3 "unique" wheels on the truck. It has 4 alloy and 2 steel rims on the inside of the duals. However the offset on the front alloys is different than that of the rear outside wheels. So the alloys can be swapped side to side but not front to back.

To do a tire rotation, all 6 tires have to be dismounted from the wheels, moved around in the X pattern, then remounted, rebalanced and put back on the truck. Cost was told to me to be $150 for each rotation. I checked with GM and my truck does have the 3 different wheels on it. Apparently some 2011 all 4 allowys are the same and others are different in front and back. GM dealer told me the 2012 manuals had this information in them regarding the different wheels.

So far I haven't done anything to them. I figure in the life of the tires I would be rotating them 4 times at a cost of $600. I can buy two or three tires for that if they wear out from not rotating. Plan to have the fronts swapped side to side and call it good.

Discount tire/ Americas Tire charged me $120 for a lifetime rotate and balance. Not bad. If you buy from them it comes with the tire.
Now, to the rotate question. My firestone's tread separated on 4 of the 6 at 40K miles. And the other two probably would have had I kept going. This came 5oo miles after a rotation where they changed the tire direction. In the past I made sure that they kept them rotating the same direction, but I got lazy and let some tech talk me into not breaking down all 6.

Put Mich's on now and after reading this thread, may not rotate at all. Will( as I always do) keep a close eye on the wear.
