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....

Bad assumption- I do not believe *anybody* has recommended ignoring the data plate on a motorized vehicle- only trailers.
All of the issues with over inflation are not present in a trailer- rather we want the tire to run cooler, and we want the sidewall to be stiff, to reduce sway. Few people will actually wear out a trailer tire.
120 psi trailer tires are certainly not the norm- I have never seen one on anything other than a semi trailer, or smaller than a 22.5. What are they, H load rated?
