The two key things you want to look at are:
1) Tire temperature across the width. If the tire is over pressurized, the center will be much hotter than the outer and inner edges.
2) Roll over on the outside edge. This can be caused both by under inflation and inadequate camber.
I just bought my second set of AD08 and I typically ran low to mid 30s psi cold.
