@ 25psi or under you will get a warning for low tire pressure. I run about 30-31 psi cold usually. 32-33 psi warm.

30 PSI cold at all four corners. Moreover, I have personally found that this tire pressure also contributes to the highest wearing tire longevity (mileage) per tire set.

43,000 miles from a set of EMT's with 3/32 remaining on the fronts and 2/32 on the rears... this is done withHot tire pressure settings... I never let my tires get over 30 psi hot.,.... this means on a hot summer day they are 25/26 cold...Many people subscribe to this thinking...
Tire rack says GY EMT's dont get good mileage... I beg to differ.
I could have taken my first set of EMT's to 45,000 miles.
AS far as the door sticker, I know for a fact that it is a product liability sticker. It has nothing to do with tire life...its there to keep people from using the max tire pressure rating on the side wall.
Running 30 psi cold will guarantee 36/37 psi hot ,when blacktop road surface temperatures can get up to 140F, which makes the tires center high, over pressure , reduces foot print, and causes premature center wear.
Tires are designed to have a specific footprint based on their application.. setting them cold has nothing to do with how they run when they are heated up...

Suppose it depends on where you are driving. Never seen my TPs go above 32 when heated up, even on a summer day in Southern Ontario. But I have seen a low TP message on a cool fall morning . Keeping them at 30 seems to work for me.
