Tire wear just on the inside tread of the tires can indicate that the trailer is overloaded. Or it could mean that the axle has been flipped over (so the bow in the axle that is supposed to be pointed up would be pointed down) and this can cause the same issue. It also decreases the axle capacity.

Most trailers do not have adjustments for the camber except to adjust the position of the whole axle. To determine if the axle is not aligned properly measure from a single point on the trailer (dead center of the coupler) back to the center of the axle on each side to see if they are the same or different distances. If they are different you can make some adjustments with the suspension to straighten it out.

If nothing above helps then there could be a problem with the axle or spindles that would necessitate replacing the axle. We have some axles, see link, but only the most common sizes as well as some more universal axle-less systems.
