Depends on several things. Even tire wear, comfort, lower friction, handling. My door sticker says 20 psi for the original GR70-15s. I ran about 28-30 in them and got even wear and decent mpg. For autoX, I ran low 40s to keep the tread on the ground.

I usually run about 32-34 psi. what i find funny is the door sticker says to run 20/26 for fuel economy.

Hi Phill,
my sticker says 30 psi front and 35 psi rear for fuel economy. you have a 79 Corvette. what does your door sticker says?
after all the infos on this topic, I'm running my tires at 34-35psi. 44 psi as DV8 says seems so high to me ...
I have seen anyway that there's nothing sure about our Corvette tires' pressure... so please everybody continue on this topic , so we can reach " a kind truth" about.
To have the proper pressure is a matter of safety too

I'll have to check tonight, but it should be the same. i was noting the optional pressure on your sticker 20/26 seems low by todays standards.

After reading all the replies under this topic, and all the different tire pressures on door stickers, I'm wondering why all the different answers. Would the different pressures on the doors have anything to do with where the vehicle is being shipped to, geographical location? That doesn't make perfect sense to me either seeing where everyone is from and considering the psi they've posted. And Aldo w/ two different pressures for the front and back, WTF?
I run a tire at max psi as I buy the tire for what the tire is about. I want it to do what it's supposed to if I decide to beat on it, so I want the pressure to be up. I've run race compound tires at a low psi in the past for better "off the line" traction knowing that it's not great for the side walls. I like a hard tire, psi-wise, as they feel better all around. I don't like over-inflating a tire as it's hard on the belts and I don't want to slip a belt long before the tire is worn out, even if it didn't prematurely wear the tire in the center. Those Firehawks rode hard and I did run them alittle soft, but not less than 30psi.
If running a tire very soft or very hard didn't kill the tire prematurely, then I see no reason why a person shouldn't do what they want.
Still don't know what the reason for so many different door sticker pressures.

How about we make a post to list; 1. the year of your 'Vette 2. the door sticker tire psi recommendation 3. the original shipping destination of your 'Vette.

Maybe we can figure out what the differences in psi info on the door has to do with; local, year, or a combination of both, or something else entirely different. ***Unless someone has this thing figured out or no one gives a crap. LOL I, for one, would like to know.
