Tire Pressure Help/Newbie
I havent had my 02 baby too long.. I have been getting a high tire pressure warning in different tires after so many miles of driving .. Yesterday I got it again .. These are stock tires on the 02 .. What tire pressure should these be at when cold and after running for awhile .. Im frustrated with this .. Thanks and sorry if this is a dumb question .
Go with the pressure stated on the placard inside the door.

It's not a dumb question, and it's one that has been discussed at length here many times. First of all - there is a D.O.T. sticker on the driver's door of your car with the recommended tire pressure - it states 30psi COLD front and rear.
But as TOMMYTRB correctly pointed out - the pressures fluctuate up as the internal temperature of the tire increases, that is exacerbated when the road surface temperture is high in the summer time.
I am not running EMT's, I run Michelin PS2's, and I live in a HOT climate where ambient temps are triple digits from May until September. I reduce my air pressure to about 27psi cold, and within just a few miles, my tires are at about 32psi.
We used to have a member here by the name of Evil-Twin. Bill is a retired GM Engineer that worked on the C5 project before he retired. This was one of his most familiar topics. He always said that if you watch a NASCAR race, the crew cheif's are constantly monitoring tire pressure and making adjustments accordingly based on track and ambient conditions to optimize tire wear and fuel economy. Good advice for us Corvette drivers, too. With rear tires costing nearly $400 a piece, you want to maximize the treadwear.
Also with the lower pressures, you'll find that that car will give you a better more comfortable ride.
