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 don't go by the data plate. They put those specs on there based on the factory tires. My Silverado 1500 comes with P-rated tires, 35 PSI.
I actually WORK with my truck, and I have Load-Range-E tires with with an 80psi rating. I keep them at 55. I always tell the tire guys doing the rotation to stop letting the air out of my tires and leave them at 55 where I keep them.
If factories actually put decent tires on vehicles and trailers to begin with, they would have to modify their data plates to show that. But just like my truck, RV manufacturers get away with using the cheapest tire possible. I always go by the specs of the tire you're actually using
and not by the sticker on the vehicle.
