The Kenda Karrier ST225/75R15 Radial Trailer Tire - Load Range E, Part # AM10303 is rated at a max load of 2,830 lbs at 80 psi. Almost all tire manufacturers advise running tires fully inflated to the recommended PSI when the tires are cold.

The only manufacturer I know that advises otherwise is Goodyear. They have some tires that come with a chart of tire inflation levels for different situations. We don't carry them in this size.
