I think the numbers quoted in the books are the maximum and not what we need to ride every day.
Over the past few months I've settled on 35psi front and 37psi rear. With this I got over 19000K out of a pilot road and over 10000km out of the rear. To me, with reasonably hard riding, this is unheard of kms previously and I put some of it down to improved tyre tech, and some done to a good mix of pressures for my weight (about 120-130KG fully laden).
