Wheel wobble at hi speed 55 mph

Bad tire; shifted layers; check for big bubbles on the sidewalls.

This sort of "wobble" is often the result of wear in rubber mounted suspension components. Control arms, trailing arms, etc.. front and rear will cause this when the rubber in the bushings begin to wear, allowing the component to shift and move more than they are meant to while driving. If not repaired this will cause premature wear in other components.

Wheel or tire abnormalities, lost balancing weight, improper rotation of tires, wheel bearing....there should be some noise associated with the wobble...any noise when turning? Struts worn or broken....torsion bar damage...or motor mount.....my best guess is a CV joint, especially if you hear clicking when turning sharply.
Manually try to turn the CV joints by hand when the car is parked...should not be a whole lot of movement....Any hesitation or rough shifting from reverse to drive ? also a sign of a bad CV joint.
It felt to me like the engine was not firing on a cylinder when I was traveling at speeds 45+....really misleading symptoms to me....but it was my CV joint all along.
Actually any one of the things I've listed could be causing the wobble. But a wobble usually indicated a bent rim, bad tire or the drive line had a bad u-joint.
The CV joints are the drive line. Good luck, work safely and I hope I was more help than hindrance.
