Although it is usually recommended that special trailer tires be inflated to their maximum air pressure, it sounds to me like the tires may be over-inflated compared to the weight of the trailer load. Example, tires are rated for 1,820 lbs at 50 psi and the trailer with cargo is only weighing in at 800 lbs. In this case the trailer just isn't heavy enough to flatten out the tire tread a little more.
You might want to try removing a small amount of air to see if this corrects the issue. Just keep in mind that removing too much air can result in excessive heat build up so you will want to be careful.
