How Much PSI When Downsizing Tires?

The sticker on my door said to have 32 PSI for all four tires on my sedan (235/45/18). I recently went to minus two and bought Pirelli CintuRato P7 All Season Radial Tires - 215/60R16 95H and would like to know if I should keep them at 32 PSI or increase it?

Start with 32 PSI and monitor tire wear. Overinflation will wear the middle of the tire, while underinflation will cause the shoulders to wear unevenly.
