Tire Pressure Sensors and 30 PSI?!

[S.V.T.]

so does anyone have the same issue as me??
the recommended warm fill is 30 psi in the tires for our trucks; however, if the TPMS gets anything lower than 30, you get that annoying warning light on your cluster..
obviously the quick fix is do fill them up around 32 cold and all it a day.
is there any way to change the level of psi to which if under, the car will warn you?

thanks.

Hmm, I thought it only warned you if one of the tires was significantly off from the others. When I went up north in Feb, they all read around 28 and it didn't complain until one hit 26. Are yours all the same?

Never had any problems when it read 28 in the Hoe, but the Onstar monthly update says NO NO.

Who recommended 30psi warm? My door label might be diffrent from yours(17inch wheels), but it says that cold fill is 32psi. Which means after driving they settle at about 34-35. I got a nail in my tire the other day with a slow leak. My warning did not go off until it got to about 26 I think.
