IIRC the original Ballistic Buggys were copies of Schumacher full and cut spikes. As in literally copies - they used Schumacher tyres with the labels removed to make the molds! But they couldn't get the compounds the same so were never really as good.

As stated, the rest of the world runs on dirt. Schumacher tyres have never won a Worlds, and are unlikely to as long as they remain on dirt.
