I will look again, but I think the tires just give a range, not a specific psi for the vehicle you are driving. - - - Updated - - - I should have been more specific, and I do have a 1500. When I had the new tires and sensors put on, I asked them to over inflate my tires because I knew I was going to be programming the sensors by letting air out of each one. As it turns out I only needed to let a small amount out before each registered, so they were all still over inflated. I only mentioned 42 as a pressure they all seemed to stop giving me a warning in the message center. I currently have all four at 38 psi, but I am not sure what should be the correct psi as the previous owner most likely ruined the other tires because they were cupped in the middle. Then again he could have been driving around with low pressure like 24 because the TPMS was not working.
