Tire Pressure-Truck and TT
I'm coming from mostly owning Truck campers and always maxing out my tire pressure to 80. I would like to find the sweet spot on my trailer and leave it and also not fittlefart too much with my truck ...

Only for trailer I calculated.
55 psi is maximum pressure , for 6750lbs , at wich no bumping and maximum reserve and livetime.Assumed Tandem-axle.
Assumed tires of TT to be ST-tires , wich are calculated in maxload for 65mph.
To get the highest pressure without bumping , I gave the tire a deflection as if the maxload was calculated for 99mph, and assumed 10% on pin, and of axleweight left , I added 11% . Deliberately did not calculate for your given estimated real weight of 6390 lbs , because estimating is always dangerous. But if so could even do with lower.
The TV also not calculated because weights estimated even more dangerous.
