I have a single axle trailer and on both tires the outside tread is worn smooth. I always (try) to run at max pressure. I have put a lot of miles on the tires. I try to run as light as I can but wonder if that is why the outsides of the tires are wearing. Would towing with the trailer closer to it’s gvwr “even” out the tires and have more even wear? Or is there something else causing this?
