Travel Trailer Tire Pressure
I'm towing a 28' travel trailer that weighs in loaded around 6,400 lbs. It has Load Range C tires that are rated at 50 max psi. Just wondering what recommendations folks have for the travel traile...

there are some exeptions to using "maximum pressure"of tires for trailers.
One is if the tires are oversised for the trailer, then you can use savely a lower pressure.
But if the tires are ST tires , they are calculated in their maximum load for a lower speed of 65m/h, and then its sometimes better to use even a higher pressure then what most think is the maximum pressure.
Up to 10 psi most tire makers alow it higher then maxloadpressure ( AT yyy PSI called reference-pressure in the official formula I once got hold of. This is not the maximum pressure of a tire as they only give on P-tires and XL/reinforced/Extraload tires.
So your 50 psi is allowed even 60 psi .
So give maximum load, reference pressure ( that 50 psi) and the speedcode or if they are ST tires.
The load of your trailer you already gave.
then I will put it in my calculator and give and advice.
