Numerous folks on this website have tens of thousands of miles of experience at ten and 15+ psi over sidewall to demonstrate that fact, myself included. But lower pressure will cause more flexing along the sidewall when you're in motion. That flexing will building up heat in the tire and increase the likelihood of the occasional blowout.
Higher pressure isn't going to unevenly wear the center? Oh yes it can. This must be a YMMV thing. I've had the centers wear first due to higher pressure and of course many on here haven't. Steel belted tires CAN flex like that. I've done contact patch experiments and saw how inflation pressure lifted the edges. We can all be right- for our circumstances. I wouldn't want to make a blanket statement of it. Who's to know what the criteria is for when the centers are going to wear out prematurely or not?
