tire pressure and extreme heat
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 an...

In any case you dont have to be afraid you will distroy your tires by the higher pressure,... but no you then give lower pressure for the temp then when colder ambiënt temp filled at max pressure.
Your "what you think"maximum pressure of tire is in fact the pressure needed for the maximum load up to maximum speed of tire (or if lower 99m/h).
for your trailer tires mayby even higher pressure is needed then that max, and is allowed by most tire-makers.
For Towingcar you should calculate the needed pressure with help of my spreadsheet, and this advice is officially for 18 degr C/65 degr F.
But still the difference is small so you can give same pressure when hot ambiënt temp filled. Little difference is compensated by taking enaug reserve but not to much things go bumping.
End advice is to be carefull with the TT tires , hot ambiënt temp filled at AT-pressure could mean that at 65 degrees its to low if you would calculate it.
If you give more details of TT and car I can give you an advice with enaug reserve for also this temperature fluctuation.
