Proper Tire Pressure EMT
The other morning I got up and the car gave me a warning that my left front and rear tire were both low. Of course it was cold outside and the warning went away right after I drove.
I was wondering what the correct air pressure was and also if people are running at that air pressure or running a little higher or lower?
Thanks

I would trust your pocket one over the readout....

As per door, 30 PSI cold is the norm. I'll run maybe -1 PSI on the rear. DIC warning comes on at 25 PSI which is way too low even in cold weather. Every 10 degree temp drop will typically give 1 PSI drop.

I would never worry too much about a 1 psi diffenence in a pocket gauge and the DIC. That's just not much difference, so whether 29 or 31 is not really that big a deal, IMO.
I would make sure the left and right sides have the same pressure (within reason) though, regardless of which method is used to check.
I've got a digital gauge from Radio Shack that reads in half-psi increments. Best I can tell, it matches the DIC readout.

30 psi at 70 degree range as it get colder I add air since it drop about 1 psi for every 10 degrees. When filling the tire, I used my digital air pressure gauge but use the DIC info just as a guideline

Pressure should be 30 PSI cold - that is what is recommended on the driver's door sticker.

I find that if I keep it at 28 psi cold the pressure quickly gets up to about 35 psi depending on how late I am.http://forums.corvetteforum.com/newr...&p=1548473051#
