IF tire tread separation is not causing the vibration, you may want to check
the rear wheel bearings themselves, both inner and outer.  Although not
common, pitted balls/rollers/races of the bearings can be a cause of the
vibration you describe, dependent on the speed of which the vibration
occurs.

BTDT with a 73 Panel Bus which uses the same rear bearings and seals as the
Vanagon (Bad outer roller bearing in my case).
