There isn't a 285/30 in either ad08r or the PS2's so it seems going larger would be better than downsizing to the 275/30's to me, but I'm just guessing.
That's why most people run 275/35/19 in the rear. That's a great size for a 10" wheel, only 20mm difference in width from the front 255/35/19 (less under steer) and available in Michelin PSS and AD08R.
