Expert Reply:
Different tire manufacturers will sometimes require a different psi on the same tire size. So you might need to check with the tire's manufaturer.
With that being said, our 225/75-15 size tires range from 50 psi on the Load Range C like part # AM10251, 65 psi on the Load Range D like part # TTWTRTM2257515D, and 80 psi on the Load Range E like part # TR225LRE.
It's rare for a tire not to list the psi on the sidewall. Are the tires old? If so I recommend replacing them anyway. If you are able to find the maximum psi one way or another you want to inflate the tires to that max when the tires are cold. Trailer tires should always be inflated to their maximum psi.
