What is is causing this to happen to my tires? (picture)

I'm wondering if once upon a time the tires on one side were not put on properly and wore like this. Then, someone redid everything so the two good tires were on the outside and the two scalloped tires were on the inside.(basically split up the pairs)

The rotation pattern for duallies requires that the front tires be the same as the rear. Then the front get moved to the outside rear, the outside duals go to the inside and the inside goes to the front. If you are not going to use the front in the rotation then someone will have to explain to me how to rotate because I can see no reason in it. When duals are bolted together they have to be thought of as a unit or as one tire. That is why equal air pressure is important.

Put on new tires, gauge them every time you use the truck and you won't have the wear problem.

As for the wear pattern I see it everyday. It is a simple cure even simple people can do. Get the gauge out and use it at least twice a week when the truck is in use.

Now I see several people mentioned rotating tires. What is the correct pattern for a truck like this? Obviously, the fronts won't go to the back.

If you can switch the front's & rear's, I hink the pattern is to put the outsides in, insides on the front, and fronts out.
