The main reason MH tires are not rotated unless, as VSheety said "irregular wear", is- the inner rims are usually steel, outer rim and front are aluminum. This means your tires would be de-mounted, rotated, and the rims put back in original position. If dual tires differ in diameter by more than 1/4", it overloads the larger one.
