Ah, yes, the ridiculous idea of sticking a car tyre on the back of a motorcycle because bike tyres are so expensive...
The first few seconds of the video clip show *exactly* what is wrong with the idea as the bike tries to corner in the wet and you can *see* just how little rubber (or tread pattern to disperse the water) is in contact with the road.
Bike tyres have a rounded profile and dual compounds for a reason...
