There doesn't seem to be any coment on that. Anyone who's moved a wheeled trolley, bike, whateveer, over damp sand or soil, may recall that the sand, or soil, sticks to the treads and falls off as the wheels pass over. In this case, it could perhaps be surface moisture. Its hard to say without actually being there. Perhaps our friends on Lunar Farside can help us with this mystery.
