I contacted engineering because I was wondering what pressure I should start out in the morning. The manufactures engineer said some try to guess what pressure to start out at so the pressure would not increase over the pressure posted on the sidewall. He said that is a big mistake! He said to inflate the tires to the cold pressure level as indicated on the side of the tire at in the morning and that the tire manufacture have designed pressure and temperature increases into the tire. I chose not to listen to what I was hearing from the installer and went with what the manufacture was suggesting. I was also told that all steel radial tires will dissipate temperature increases better so I shouldn't see as great of a temperature pressure increase.
