My truck stickers say rear tires to be at 70 PSI. The tire says max PSI is 80. I run at 80 PSI when towing. The manufactures allow for expansion. Don't know the range but I'm sure their calculations are within normal ranges. I wouldn't be too concerned. Your TPMS will warn you if temp/pressure is exceeding nominal ranges. Assuming you have a TPMS. At 80 PSI running at 70 MPH with a tire temp of 135 I haven't seen the pressure raise more then 3 or 4 PSI.
