Reading the recent 4 down vs dolly thread reminded me to post this idea I came up with that stopped wet tire wheel spin when loading our toad onto our 2016 Master Tow dolly.
Our Taurus has pretty wide tires and if the tires are damp, it is easy to spin them at the pavement\dolly ramp transition. The fix was simple: I brushed on a 2 -3" wide coat of paint, sprinkled some roof shingle granules onto the wet paint, pressed the granules into the paint, let dry, the added another coat. (found the granules in our roof gutter, thought sand granules would be too small to be effective).
The pic was taken after 6 load\unloads and the granules and paint seem to be holding up well.
