My tires are Goodyear 245/70R/19.5. After weighing, I'll be running 90 psi in each tire. I see on the Goodyear Load/Inflation Chart that there are some weights that are in bold print with a letter following: For example: 4080(F). I assume the "F" is a 'load rating' ??. My tires, however, are "H' rated which is not even shown on the chart. Are these letter ratings indications of the tires number of plys? Also, do I ignore the fact that my "H" rated tires are not even shown on the chart and still go with the 90 psi indicted by actual weight? Thanks, Larry

At what ambient temperature should that adjustment be set if one drives from -30F to 90F?
