The pressure shown on the door sticker. 30 PSI Cold. It doesn't matter what brand or model tire you install the pressure is determined by the car manufacturer based on the size tires that will fit the car.

It is more noticeable in the motorcycle industry where different tire manufacturers will deviate from the factory suggested pressures more often.

Of course, you can do anything you want re tire pressures but maybe, unlike the motorcycle tire industry, not every tire mfr. who makes a size that fits the C6 has done tests to determine the correct pressure for any car, including the Corvette. For that reason, I'd leave it up to the car mfr., Corvette/GM to tell you what is the best tire pressure for the car. But, that doesn't mean that for your individual driving habits you might want to change it slightly to a different pressure, either up or down a pound or two. Just start out at 30 and adjust as you become more aware of how and where you drive.

Not exactly sure what you are saying there, but I was not saying 30psi is wrong, just it came from the manufacturer that made the OEM tires when they tested with GM.
Personally I liked 30psi on the original tires, when I switched to Michelin I preferred 32psi, now I have Bridgestone Potenza's and have them at 31psi. Actually surprised how much difference a couple pounds made in the feel of the Michelin's.

30 psi cold, but the normal running temps are 33-34 when hot during the summer. In the Fall, I put 32-33 psi(cold) in my tires as they don't heat up that much, and I end up with 33-34 degrees once they heat up.
