Generally, trailer tires wear on just the outside of the tire when the trailer is overloaded (which could be the case with more weight on the rear axle at the rear), there is an issue with the suspension being misaligned, or they are not fully inflated to their maximum psi. I'm not sure what your tire's max psi is, but make sure you want inflate them to the maximum psi to prevent uneven wearing, and you can find on the tire's sidewall.
