We used to rotate tires on farm duallys (which requires taking the tire off the rim and moving to a different rim in many cases), but found it actually cost more overall than never rotating them. So now we just replace front tires as needed. It's usually 2 or 3 sets of front tires per set of rear tires.
I'm sure you will get many opinions on this
. If you have a trusted tire expert you use, ask them about it.
