Just an FYI:
Evenness of tire wear - that is whether the tire wears in the center or the shoulders - is only slightly related to inflation pressure. Put anther way, inflation pressure has a small effect - other things have a much larger affect than inflation pressure.
There has been a trend for pickup truck manufacturers to go to larger than the minimum size tires - and inflate them so. This is because of the Ford/Firestone situation a few years ago. As a result, there is pressure (pun intended) on tire manufacturers to adjust their tires so they wear more evenly at those higher pressures. I suspect enough time has gone by that the latest offerings have been adjusted.
So I don't buy using the load tables by themselves in order to maximize tire wear. I don't like the idea of running tires at the minimum inflation pressure needed.
