Normally I would agreee but there have been several examples of people on this board having greater center wear (myself included) with lower PSI on the rears. The majority of people with 34 PSI and up report normal wear.
Someone had a theory about tires spinning at higher speeds for mostly highway driving. Lower pressure could allow the center of the tire to expand more and bow out/wear more if most of the driving is done on the highway.
I know as soon as I put my shiny shoes back on they will be going up to 35 PSI to see what happens.

Self-importance is our greatest enemy. Think about it - what weakens us is feeling offended by the deeds and misdeeds of our fellowmen. Our self-importance requires that we spend most of our lives offended by someone. -- Carlos Castaneda
