Everyone needs to remember to set tire pressures "cold". DO NOT try to compensate for the normal rise in temperatures that driving causes and DO NOT try to compensate for ambient outside temperatures. Also, "Cold" means you haven't driven on them! It has nothing to do with ambient temperatures. For instance, I set a cold tire pressure in northern Utah in Jan. where the outside temps. are 12 degrees to 105 lbs. I then set the same 105 lbs. cold pressure in Phoenix when it is 105 degrees outside. Same "cold" pressure setting, but vastly different ambient temperatures outside. This is a very common mistake people make.
