Same here - about 44 psi all aroundFor the tire related issues...did you ever check their inflation after you bought? My truck came from the factory with it's tires overinflated by 15 PSI...made a noticeable (positive) difference when I aired them down to spec. I have the off road group tires, so your experience may not be the same, but worth checking if you haven't already.
