Yup, I also noticed exactly what you described. And looking at the video on the passenger side is smooth, no wobble in the tire whatsoever. I decided to swap rear and front driver side tires and record another video. I don't see much tread shifting with this wheel.

The tires have been balanced twice now, last being at Toyota. My suspicion is that I may have damaged the wheel off road about a year ago. Hit some pretty hard ruts and drove it a little too hard on some trails north of Vegas for over 45 miles. I feel I might of thrown the wheel out of round.

That being said, the ride seems smoother now with that wheel on the rear. Here is a short clip from my GoPro.
