The one I remember hearing about was a graphite powder that would make
the carcass more conductive.  In use, a quantity was injected in the
tire before it was inflated.  NB:  This material may be limited to
tube tires at present.

The wheel bearing grease also caused some problems by insulating the
tires from the frame, so the bearing assembly would have a spring that
bore on the bearing cap and on the spindle to keep them at the same
potential.
