I think the recommended pattern is to move the rear tires straight forward and cross the front tires back to the rear. I do just the opposite, moving my fronts straight back and cross the rears forward. For anything but stock tire sizes, rotate every 5,000 miles or sooner.
Picturing A as your drivers side tire:
AB
CD
would end up as:
DC
AB
If you have a matching spare, add it to the rotation:
AB
CD
E
would end up as:
DC
AE
B
This got me 60,000 miles out of my last set of BFG MT's with enough tread left to sell the set for a hundred or two.
