The unsprung mass of a fat tyre is only the mass of the bit of tyre on
the road - at least for small bumps. Modern skinny tyres have almost no
give, so the suspension has to do all the work. And the result is a
harsher ride, poorer handling, and vulnerability to potholes.

Some think they look better. Which overrides the other three.
