Tire Pressure - MAX vs DATAPLATE
A LOT of replies to tire threads recommend running the trailer (and I assume also car/truck/motorhome) at sidewall max psi instead of the dataplate psi. Why? My trailer tires have a max psi of 120....

120 psi?? What is the tire designation on the trailer tires and brand? Big difference in what to do between tire types and what they're on. Are the tires presently on the trailer the same as what's on the placard? They can be different and if run too low, serious damage from heat can occur.
Go to RV tire safety dot com and read about ST tire inflation from a tire engineer.
Good point and good recommendation for those that are clueless about ply shear on close spaced axles on our conventional trailers vs tires on a car/jeep/suv/truck/etc. Apples vs oranges.
The OP is probably out camping and enjoying his trailer....so when he gets back maybe he can clear up the 80 psi placard with 120 psi rated tires.
