Actually I verified the opposite when I rode a street bike. Lower pressures cause the tread to flex and heat up. The center of the tire gets the least air/cooling, so it wears faster when pressures are low. Higher pressures avoid this heating of the tread, and higher pressures DO NOT cause your tires to balloon out in the center as some might suspect. The inside of the tire carcass is round, so the more pressure you put in it, the more firmly the tire retains its designed square shape. It is when you put too little pressure in the tire that centrifugal forces can pooch the center out."

I run my rears lower pressure to prevent the middle of the tread from experiencing accelerated wear.

Can you prove your comments above? I may change my habits.
