I make an analogy with downhill skiers; they want to keep their skis on the snow as much as they can because that is quicker. Similarly if your tyres are rock hard you're going to spend longer in the air as you bounce over surface defects. And recommended tyre pressures are recommended for what: perfectly smooth roads? cobbles? wet weather?
But try telling that to a young courier with a bad attitude and a Joe Blow and all you'll get is a packet of Werther's Originals thrown in your face.
