Correct tire pressure for 2006 c6 runflats

[dpcfoc6]

Can anyone tell me the correct tire pressure for my stock runflats on a 2006 c6?

Look for the factory decal on the doorjamb or under the hood. I keep mine at 30 pounds cold.

30psi is factory spec. On my first set of tires I kept mine at 30 but when I had to get new ones I noticed the centers were worn more than the outsides indicating over-pressure. I have used 28psi cold since replacing my tires and have had even wear across the tire.

Since "cold" is subjective, I use 60F as cold. Let's face it, "Cold" means 2 different temperatures. In Dubai "cold" an be over 100F and Winnipeg can "cold" if only < 0F.

I don't know what the difference is in 100F separation, but I've seen my tires "grow" from 30PSI to 38PSI in a half hour. When they "cool" they return to 30PSI. I live where the temperature doesn't change much also. Take today for example: from day to night, the change is 6 degrees F.
