Proper Tire Pressure

My car originally came with the Bridgestone Potenza run-flat tires. I didn't like the way the road felt on those, so when it was time for new tires I got Continental ExtremeContact DWS's. Do I still use the tire pressures listed on the sticker inside the driver door, or is there some kind of different pressure amount that I need to use now that I am not running on run-flat tires?

I did the same conversion except to DW's. My very knowledgeable wheel and tire tech is running the same recommended pressure as in the door when he installed them.

I changed from those Bridgestomes, to Michelin PSS'. I had advice from numerous sources, tried several suggestions, but the best for ride, handling and ensuring even wear was exactly same as the RFTs in other words what was on the door.

what tire size you running and what does the door jam tell you to have running?

my car suggested i run 32psi all around with the stock run flats. i switched to non-rfts and i run 36 psi front and 40 psi rear measured in the morning at about 7am while the car is parked in the shade. Once i drive on these tires, my psi increases up 3 psi to 39 front/43 rear

I'm using Bridgestone PP S04, 235/40/18 front, 265/35/18 rear and I'm using the tire pressures that are on the door sticker.
