I hear what you're saying, but shoulder wear can result from a number of possible factors, underinflation/overloading being one of them. Other factors include improper alignment (toe in or out, camber positive or negative) or tires being out of balance. So, without an inspection of the tires it would be impossible to determine which was the primary factor, or if it was a combination of two or three of these things.
I also experienced excessive shoulder wear on my OEM tires over similar miles at Nissan's recommended pressures and the recent alignment check at the time of replacement found only the right front slightly off. (I don't remember what it was at last rotation.) Upon asking, the installer suggested the shoulder wear might be due to the main highway around here being fast and windy (highway 17 between Santa Cruz and Silicon Valley) but I don't see that kind of wear with my RAV4 (also at vehicle's recommended PSI).
I think I may try adding just a couple pounds of pressure. I wonder if Nissan screwed up their calculations on the recommended PSI for the LEAF.
