Wheel alignment

Has anyone ever done a wheel alignment for their MY? I got one done (not by Tesla by a third party)the other day because I got new tires and my car was pulling to the right. After my alignment I noticed that when on autopilot my car seemed to have trouble staying in the middle of the lane. It would go towards the right then to the left and again to the right. The car would overcorrect and go the other way not staying in the center of the lane. Has anyone else had this problem? And what was the solution? I have a Tesla service appointment tomorrow, I'm definitely going to have them take a look at it.
