Max PSI rating on Trailer Wheels?
My trailer's Alloy wheels are 15 x 6, 5-lug. The load rating stamped on them is 2150 lbs. It came with 225-75-15, load range C tires, which run 50 psi. These tires are are marginal IMO for the trail...

It is always a wise idea to get the load / pressure chart for the tires from the tire maker themselves if possible. There is no tire I use that gets max inflation on the sidewall. that is only if putting max rated weight on the tire. Even my commercial semi truck, though the drive axles are rated for 34,000 lb, the tire pressures for that are 95 lb from the load pressure chart, though the sidewall says 120 lb. Must be right, as I got 447,000 miles out of the last set of drive tires on that truck.
You want maximum performance for braking, water, etc and running the correct pressures for the load is critical for maximum effectiveness of the tire.
Even the tires on my Chevy 2500. The OEM recommended is 60 psi up front, 70 in back. But that is if the truck is at maximum GVWR. I am using BFG KO2's on that truck, and BFG recommends 50 front 45 rear when empty. Air up more as needed when loading up. Truck handles, brakes, corners, etc much better when following the load pressure chart. After all, the vehicle or trailer OEM did not make the tires. The tire maker did. they ought to know the best pressure to run in them based on weight.
