Disadvantages of Overinflation
An overinflated tire is stiff and unyielding and the size of its footprint in contact with the road is reduced. If a vehicle's tires are overinflated by 6 psi, they could be damaged more easily when encountering potholes or debris in the road, as well as experience irregular tread wear. Higher inflated tires cannot isolate road irregularities as well causing the vehicle to ride harsher and transmit more noise into its interior. However, higher inflation pressures reduce rolling resistance slightly and typically provide a slight improvement in steering response and cornering stability. This is why participants who use street tires in autocrosses, track events and road races run higher than normal inflation pressures.

I agree that
over inflation may wear out the centre of the tread faster. I personally doubt that max sidewall would do that. Why would a tire company who's warranted tires will be installed on many different cars with different
recommended pressures build a tire that would wear out prematurely when pumped to the max sidewall? In my own experience I have always run max sidewall and never had the centres wear out faster than the edges. I have had my edges wear out faster from cornering fast though.
