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 tire pressure?

I just set mine at the proper cold inflation temp. and go as normal. The change in outside temps. happen gradual and will only rise by a couple pounds if that. You can check cold pressure each day before you set out on the next day travel. That is how I do mine.

I check my pressure each morning before hitting the road.

TT here, but same principle. Check your pressure before you leave, drive happy! Do you add or remove air in your truck or car tires because you drive to a different temperature climate? If you don't adjust your tow vehicle tires, why adjust your trailer tires?

You need to check your tire pressures and adjust accordingly as you move from cold temps to hot temps...or the other way around, in both the trailer and tow vehicle. In your scenario, failure to do this will result in over inflated tires going north to south, or under inflated tires going south to north.

That should get you well into your trip before you have to worry about adding more.
