sounds like you may have multiple problems, one problem could be a lateral runout on one tire.
Rotating tires does not change your alignment. Putting a tire with excessive lateral run out from the back to the front can cause a pull to one side. If you rotate back, does the pull go away?
You may also still need an alignment and balance. hard to say over the net
