On a slightly related note, I always saw flat spots on the tires of
rental airplanes and I wondered if I'd been responsible for any of them.
Now that I've had the same set of tires for hundreds of landings I know
it must be harder than I thought to flat-spot a tire.

no....
the tyres are out of balance.
after takeoff when the wheel finally spins to a stop the heavy part of
the wheel naturally points down. this means that the same part of the
tyre actually bears the wear of touchdown as the tyre is spun up to
landing speed.
thats why there are flat spots.
