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....

In 55 years of working on vehicles and trailers, I have NEVER seen a tire fail yet that was inflated to vehicle/trailer MFG. recommended pressure. If tire is over inflated by 50%, it will wear more in the center, and there will be less "Foot Print" of the tire in contact with the road. So in an emergency stopping situation you will have maybe 1/3 less grip to stop your trailer. Also ride of trailer will be a lot more harsh.
