ok.. ok.. Im confused... so lets say..
I'm out in santa cruz.. inflate my tires to 30psi
THEN
: pick up a fat chick weighing 325lbs
: Cruse to Yosemite w/ 12K elevation
: 105 Deg w/ 80% humidity
: Then while driving I accidentally roll into a 3 foot deep puddle submerging the tire...
What would be the correct TPMS reading?

Hey, if GM says 30PSI, I'll go with that. On the other hand, I've already had to replace wheels because of the bent/cracked wheel issue. My question is, "Is there a better PSI to set so that there is less stress on the wheels (OEM wheels)?". Just asking, no flames please.

My opinion: Unless you are running the car REALLY hard, or racing, and are still running the stock tires/wheels/suspension pieces, go with 30 PSI cold.

A few PSI here or there is not going to cause problems. You don't need NASA levels of precision on a street driven vehicle. The most important thing is to check your air pressure often as tires lose air over time. So if your like the average 'Vette owner and you don't drive many miles you might be in for a surprise the next time you pull the car of out of the garage.

I raise the tire pressures to about 33 when I put it away, and normally I have about 30 PSI in them in April when I activate the car. This is over 4 Vettes in a 22 year period, so for me this is a sort of constant.

But ambient temperature is ambient temperature. If you are typically driving when it is 90 degrees, set the air pressure to 30 psi when the "cold" temperature is 90. You may well end up leaving air out of your tires.
Hang in there!

Resurrecting this thread to pose a specific question. In this thread it seems like 30 psi cold is a consensus proper air level. That is also what is on the tag inside the driver door.
Question: does anyone think that should change if I have swapped out the OEM summer only tires for Pilot Sport A/S 3+? Mine is a 2016 Z51.
Thanks...!

I raised the air temp in all 4 of the non-run flat Michelin PSS tires on my car to 32.5 psi. The computer reads the running tire pressures at about 36-37. Have had no traction or any other problems using these tire pressures.
Personally, as between 30-32.5, I don't think it really matters for the street.
I just raised the psi a bit because it made me feel better in terms or providing some additional rigidity to the extremely low sidewall PSS tires in order to reduce the possibility of damaging the bend/crack prone wheels on the car.

My door jamb reads 35 PSI. Sometimes, in the hot Fla. summers, on the highway; the pressure will go up to 40PSI!
NOTE: I did get 40k mi. out of the PSS tires, keeping them st 35 PSI cold.
