Air Pressure 19.5 tires
As in my earlier post showing new 19.5 wheels and Dyna Trac PD890 16 ply load G 19.5 tires I have question regarding air pressure. Firestone near me removed my other wheel/tire package and mounted my 19.5 visions and tires last Friday for free. Had them inflated fronts to 80 psi and 100 psi in rears I thought but went and check tire pressure cold this morning and fronts were 72 psi and rears were 92 psi. Temp was 79 with 84 % humidity. No direct sunlight on any tire. Drove 20 miles on highway with TC/truck combo to a doctors appointment and checked them there. 80 psi fronts and 100 psi rears. Should the cold readings be 80psi and 100 psi or is it ok the way psi is when tires are heated up?
