I live in Columbia, SC and will be headed to Florida Keys later this week, pulling my travel trailer. Morning lows have been around 75F and highs around 100F. I've always filled my tires on truck and camper to the max labeled on the sidewall. I do this in the early morning before the sun starts beating down. Do I still fill them the same way given this extreme heat or do I need to back off the pressure a bit? Thanks.

Why do you run max pressure versus recommended pressure? Manufacture's recommended pressure gives you a safety range to handle increases in ambient temp.

Don't make this more complicated than it is....(Rv'er tend to make things complicated.)Early morning - check and fill your tires to the max as recommended on the side wall and the placard on your tow vehicle...

Yes, on the trailer tires, run at full pressure. Lowering it is actually harder on them as they have to flex more and that makes even more heat.
