I did a search could not find the answer.

What is the proper tire pressure for the '07 OEM 20" wheels?

 

It's on the driver's door sticker. Without looking, I think it's 35 psi.

 

Mine came with 17's, just wanting to make sure I have the right pressure in my new 20's

 

My LTZ came with the 20's...the door post label say 32....the dealer had put in 40.... I though the tire pressure guage iin the info center was wrong but I checked it. I let out 8lbs and now have 32 at cold reading.....ride is much better

 

On the tire is says with max load maximum of 44 PSI. I run 37 in all of mine, steers a little better, than when running 32.

 

Is that 37 when cold? I notice the onn the info center that the pressure rises when warm about 5 psi.

 

My door says 32. I run 35.

I let them get to 32 cold reading (as it got colder this fall) when I checked it they ran about 37 on the highway with that setting. I'd be curios to see what your running temp was when you had them 40 cold.

 

I am not sure what you mean by running temperature. It was 55 degrees outside. And the car had been sitting over night.

 

Pressure should be checked cold -After sitting or being driven a very short distance.

Mine is about 32 cold and once on the highway awhile the sensors read about 37.

No biggie-just curious--- I guess if a higher pressure creates less rolling resistance it may not raise as much as mine did...so 5psi or less I suppose.

 

Thats what I am seeing on mine. I never checked the warm psi when they read 40 cold, I immediately reduced them to 32.
