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....

Here's an example:
The company I work for has a fleet of vehicles we can use when going out in the field. One is a chevy 2500 long bed extended cab. Originally from the factory it came with load range c tires with a max PSI of 35. That's what the data plate shows on the door. When the tires were torn up on a rocky road, they were replaced with Load Range D tires. The sidewall shows max is 80 PSI
Similar with a Jeep Cherokee. The tires were replaced with a higher load range tire.
That being said many tire manufacturers on their websites provide charts which indicate the acceptable PSI based on the actual load.
I always keep my tires inflated to the Max PSI indicated on the sidewall. I don't have the time to adjust the pressure depending on load I'm carrying.
