That's a good point. I missed that, and I shouldn't have because,
regardless of recommenations, when I had a Ford F150 with special
suspension to carry over 2000 lbs, I often had my rear tires
inflated as much as 10 lbs higher than the front.

Someone can correct me if I'm wrong but, it seems to me of your
tires are carrying less load than the tire pressure is set for,
the wear should be in the middle, not the outer edges, since the
weight isn't there to flatten the tire right down to the road
surface.. (?)
