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....

I think that comparing cars/trucks with trailer is comparing apples and oranges to a certain degree.
I think the trailer tires should be closer to sidewall max pressures because of the stresses that the trailer puts on its tires. Seems to me a fully inflated tire will withstand cornering and scrubbing issues better than a tire that is softer and only partly inflated. But that's strictly IMO.
FWIW however, Goodyear did have a notice on their website that recommended inflating RV tires to max sidewall pressures.
