I agree on the road camber not being an issue. I have a different trailer now, but the same exact model tires on it. I drive the same roads every year while camping. I have zero wear on theses tires. Close to the same miles (10,000) on both trailer tires. JMO nut it's kinda weird that both tires on the same side are wearing differently. Whats the chances of both bad tires being put on the same side? Coincidence? Maybe, but I'm sticking with the misaligned axles theory. Before I plunked down $250.00 for two new tires, I'd take it somewhere that knows how to check things out 1st.
