Without seeing the actual pattern, it sounds like the tires are cupped on the inside edge. The wear on the inside indicates the axles are slightly bent upward, making the contact patch of the tire on the inside edge. The cupping could be due to a couple of factors, with suspension alignment being one of them, but in many cases it is an unbalanced tire.
It doesn't take much to change the location of the contact patch by having axles that are not exactly parallel to the ground. A good shop can get them adjusted, then new tires balanced, and I think you will be good to go.
