Symmetrical object won't rotate on axis evenly This is a wheel with bones and constraints to help it roll and turn. I don't know what I did in the process, but my wheel no longer rotates symmetrically like it used to despite not manipulating it at all. 

I've tried Origin to Geometry, Cursor to Center, and resetting the Rotation, but it doesn't fix the problem. 

Is there a way to fix my wheel's rotation?
Set Pivot Point to Median Point


Go to Edit Mode and select vertices in the middle that creates a circle so your pivot point is now at the exact center, something like at this screen:


Press ShiftS > Cursor to Selected to move the 3D cursor to that pivot point


Now exit from Edit Mode and set the object's origin to the 3D cursor by pressing the best shortcut in the universe CtrlAltShiftC, select Origin to 3D Cursor
