Good article, it dispels the myth that tire pressure doesn't matter and
that the sidewall will support the tire regardless of the pressure.

What is not really true, in many cases, is that the reduced rolling
resistance of higher pressure tires is offset by vibration losses. If
the bicycle has suspension, then these vibration losses are not present.
And of course on smooth roads, the vibration losses are minimal even
without suspension.

For example, my Dahon and my Bromptons both have suspension to reduce
vibration transmitted to the rider, an especially important feature on
smaller-wheeled bicycles. A great many hybrids and sport touring bikes
also have some sort of suspension, a suspension fork and/or a suspension
seat post, and of course nearly every mountain bike sold these days has
suspension.
