I know that everyones mind is already made up on this issue already, but I'm going to add my personal experience as well. I have read a lot of claims that running tires at max. pressure or a little higher will not increase tire wear and may reduce it. My experience is just the opposite. I have never had a tire wear the outside edges off from running too soft. I have however had 2 sets of tires wear out in the center on my '93 villager at only 35psi. My work van was wearing the centers out running at recommended tire pressure. I am currently running them 10psi low and getting more even wear. My son put oversize tires on his Ranger and experienced severe center rib wear after only 10k miles at 35psi. I have also seen lots of other cars around with noticeable center rib wear. My Rondo is wearing the inside edges off the tires but that is because of excessive negative camber in the design. I have been running the tires at 40-45psi to help compensate but the ride is terrible, the fuel savings is minimal and I am worried the higher pressure may even be adding to the problem because of less sidewall deflection. I'm sure cars with small, narrow tires will benefit from running a little higher pressure, but many cars today have much larger and wider tires than they need to IMO. I just don't think that it's right to be making blanket statements like "max rated tire pressure is always best" or "will never increase tire wear". There are always exceptions.
