Okay, higher pressures increases the steering response but again that is because it has reduced the grip. It is the reduced grip that gives you the increased fuel figure.
Here in the UK there is a lot written about over-inflated tyres increasing wear in the centre of the tread.

That picture looks super fishy to me. It's artifically blurred down the center, and you don't see a great reduction in depth at the top. Almost like they couldn't easily find evidence of radial tires wearing out in the center to go along with their article, so they had to make something up.
