Tire pressure before going south
I am curious what others do about air pressure in your fifth-wheel tires. If you set it at proper PSI in the north at 30 degrees and then end up in FL at 90 degrees, what effect will that have on the ...

I would like to also mention my experience with nitrogen filled tires. As an experiment I filled one tire with nitrogen to see if there is any difference in temperature vs pressure as claimed by those selling nitrogen. The bottom line is there is no measurable difference because of the accuracy of the TPMS at 1%. Aircraft use nitro to minimize a potential fire hazard and race cars use nitro because of the temperature extremes the tire run at (200deg). Trailer, truck and passenger cars do not share the same environments and therefore it is a waste of money to fill those tires with Nitro. As it turns out physical laws support his my experience.
