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 ...

Traveling in hot weather, as we usually do (even at 4-5 AM in AZ, it can be well > 90F in the summer), I'd rather have my tires at max pressure for more heat dissipation. Yes, I =may= lose a wee bit of contact patch...but I may =not=, as the tires will be hotter and more flexible, so will tend to have a better footprint. Now, traveling light, or in cooler weather, I have no problem dropping from 80 to 70 psi. I'm placarded for D's at 65 psi anyway, so that extra 5 psi is just more safety margin, IMO. I check temps on my tires and hubs all way 'round at every stop, but not pressures, unless I notice anything unusual. Next FW will have a TPMS, though. :-) I check pressure every day I travel.
