Assuming that the repairs and the alignment were done correctly, then the only variable left is the new tires.

I find that I am very sensitive to alignment and wheel balance issues. If its even a small amount off, I can feel a difference and it bugs the crap out of me. I would suggest that you have the alignment checked just to be sure. Take it to a good shop and tell the tech about the problem and ask him to specifically make sure that everything is within spec.

If the alignment is ok, then you'll know that its the new tires.
