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.
Sorry, but this is not much of an example. You failed to give any facts which support the decision to inflate to max PSI. It only seems that load range C tires were not suitable for the job.
