I have these mounted on a 14k trailer that I usually haul two sxs on from Indiana to Tennessee or southern Kentucky with no issues so far. I occasionally haul 11 5x5 round bales on the same trailer. After swapping to these tires from the previous, they seem to squish much less and the trailer pulls as if it was much lighter. I am very pleased with them as they are showing no obvious wear on the tires.
