I did a tread wear test at varying tire pressures on a set of tires once:

I noticed almost no change in the wear rates running the (44 PSI max) tires at both 32 and 
44 psi.  When I finally bumped up the pressure to 44, the handling of the tires was 
greatly improved.  At 32 psi, they squealed and slid around even slow turns, at 44 they 
cornered so much better.
