GMC door sticker on my dually says 70psi front, 65psi rears.....when loaded for big trip I am just over my GVWR.....I run 70psi front, 72psi rears.....tires run good temps at speed and corner really good. I have had an issue with two OEM valve stems rubber blowing out like it was rotten....GM replaced all 7 with solid metal screw in stems under warranty, but insisted there was no problem or recall on OEM ones....hmmmm?
