30PSI cold. Higher pressures if you do autcross.

30 to 34,is what most people run any higher will set off the tire sensors.

Thanks for all the feedback. Loads of good information there. But as I am not part of any organized racing teams I'll just stick with 30psi cold. Just wanted to make sure I wasn't doing something stupid with my first Corvette.

It's kinda hard to go wrong with the inflation because you'll get a DIC alarm if the pressure goes below 27psi or more than 38 psi with any tire.

So I chose to underinflate the tires to about 27psi in the summer, so that when the tires heat up - they get to about 31 or 32psi hot.

This time of the year, 27psi is too low, and I inflate them to 29psi and they get up around what I think is the sweet spot of about 31 or 32psi hot.

The bottom line is to keep a close eye on your tires and make adjustments accordingly all year. That's what the racing teams do - they adjust inflation according to their desired goals - whether that's tread life, certain handling characteristics, fuel mileage, etc. Paying close attention to the tires is the single best way to optimize tread life.

Oh yea

.....you and I may be in the minority though

...I keep mine adjusted seasonally to read 30-31 hot and that meeans less than 30 cold depending on ambient temperature.(that little GM sticker that says 30 cold is generic). In the summertime, if I keep 30 cold it reaches up to 36 and thats too much and will wear the center for sure. Thats my .02 and I'm sticking with it

Run all my tires between 28 and 32 PSIG cold. usually only drive the car once a week in the winter and have had no problems.
On the track, even in the winter, take them to about 26 PSIG to run.
