I run the tires on the Chevy at 80/55 when towing and when not towing. I wore out a set of Firestones at 38,000 miles but the wear pattern was near perfect. No indication what so ever of over or under inflation.
The trailer tires are set at 75 psi and so far no under or over inflation wear pattern.

BTW- For those that do not know...
Over inflation wear pattern is when the tread is wearing more in the center of the tread than on the shoulders.
Under inflation is wearing on both shoulders more so than down the center.
