I run about 36psi in the cooler months. When it gets hot I bump it up to around 40.
Probably not a bad idea to consider 35psi a minimum (definitely come summer), just on principle. Load tables don't go lower than that for LT tires which should tell you something. The official procedure these days for pressurizing LTs that have been switched from the OEM P type tires of the same size is to add around 10-15psi so as to avoid a reduction in OEM tire load reserve, thus, I assume, the reason the shop set them at 45psi.
Here's something in chart form for more context.
LT tires need more air pressure.
