The trouble with motorcycle tyres is their lack of sidewall strength. Then bike leans into corners, and uses a round profile for the footprint. I car uses a flat footprint and so needs more sidewall strength.

late to the party but...
actually that's backwards. Motorcycle tire sidewalls are generally quite a lot stiffer than automotive sidewalls, because the motorcycle tire must be limited in side to side movement of the rim with respect to the tread, so that steering and stability don't suffer. a weak sidewall will allow too much movement between the tread and wheel before the motorcycle reacts to steering and cornering inputs and responses.
As someone who has changed both, by hand, over the course of 4 decades, trust me, I'm an expert.
Another common misconception is that motorcycle tires are generally softer than car tires, but again, the reverse is true. motorcycle tires have much higher tread loading than cars (as they're contact patch is usually less that 50% of an equivalent car tire for a given tire size) and the compounds have to be relatively harder to get any acceptable life out of the tread...
...which, for bikes, is usually about 25% of an equivalent car tire.
