Possibly... It could also be a bad tire, but wear on the inside is often an indication that the bottom of the wheel is cambered outward causing the load to be carried on the inner portion of the tire. Rotating the tires and observing them over time is one way to determine if the tire is the problem or if there is a something amiss with the spindle or axle alignment. Personally I would rotate the tires and replace the worn one as I've come to distrust suspect tires. I would also get the trailer weighed to verify it doesn't need to be put on a diet. If the wheel bearings check out, find a shop that can check and adjust the axle alignment. They can also determine if the arm is somehow bent... That might indicate an axle replacement is warranted. If you look under the trailer at the axle, you may see that it appears bent near the middle. This is how trailer axles are aligned and is normal. It should effect both sides equally. Unusual tire wear should be investigated to avoid a possible breakdown in the middle of nowhere.
